So, we have this operation defined as a⊗b = a²/b. And we need to compute [(1⊗2)⊗3] - [1⊗(2⊗3)]. Then choose the correct answer from the options given. Alright, let's break it down step by step.\n\nFirst, I need to remember that the operation ⊗ is not associative, right? Because the problem is asking for the difference between two different groupings: (1⊗2)⊗3 and 1⊗(2⊗3). So, the order in which we perform the operations matters here. That's probably why there's a subtraction between them.\n\nLet me start by computing each part separately. Let's tackle the first part: (1⊗2)⊗3.\n\nStarting with the innermost operation, which is 1⊗2. According to the definition, a⊗b = a²/b. So here, a is 1 and b is 2. Plugging those in: 1² / 2 = 1/2. So, 1⊗2 equals 1/2.\n\nNow, we take that result and perform the next operation with 3. So, (1⊗2)⊗3 becomes (1/2)⊗3. Again, using the same definition: a is now 1/2 and b is 3. So, ( (1/2)² ) / 3 = (1/4) / 3 = 1/12. So, (1⊗2)⊗3 equals 1/12.\n\nAlright, that's the first part. Now let's compute the second part: 1⊗(2⊗3). Again, starting with the innermost operation, which is 2⊗3. Applying the definition: a is 2 and b is 3. So, 2² / 3 = 4/3. Therefore, 2⊗3 equals 4/3.\n\nNow, we need to compute 1⊗(4/3). Here, a is 1 and b is 4/3. Using the operation definition: 1² / (4/3) = 1 / (4/3) = 3/4. So, 1⊗(2⊗3) equals 3/4.\n\nNow, the problem asks for the difference between the two results: [(1⊗2)⊗3] - [1⊗(2⊗3)] = (1/12) - (3/4). To subtract these fractions, they need a common denominator. The denominators are 12 and 4, so 12 is the common denominator.\n\nConverting 3/4 to twelfths: 3/4 = 9/12. So, 1/12 - 9/12 = (1 - 9)/12 = -8/12. Simplifying that fraction by dividing numerator and denominator by 4: -8/12 = -2/3.\n\nHmm, looking at the answer choices, option A is -2/3. So, is that the answer? Wait, but let me double-check my calculations to make sure I didn't make a mistake somewhere.\n\nFirst, checking (1⊗2): 1² / 2 = 1/2. Correct. Then, (1/2)⊗3: (1/2)² / 3 = (1/4)/3 = 1/12. That seems right.\n\nNow, for 2⊗3: 2² / 3 = 4/3. Correct. Then, 1⊗(4/3): 1² / (4/3) = 1 / (4/3) = 3/4. Yes, that's correct.\n\nSubtracting 3/4 from 1/12: 1/12 - 3/4. Convert 3/4 to 9/12, so 1/12 - 9/12 = -8/12 = -2/3. Yes, that all checks out. So the answer should be -2/3, which is option A.\n\nWait, but let me think again. The operation is defined for all nonzero numbers, so we don't have any issues with division by zero here. 2⊗3 is 4/3, which is fine, and then 1⊗(4/3) is 3/4. Correct.\n\nAlternatively, maybe there's a different way to approach the problem? Let me try expanding both expressions using variables to see if there's a pattern.\n\nLet’s denote the first expression: (a⊗b)⊗c. Using the definition:\n\nFirst, compute a⊗b = a²/b.\n\nThen, take that result and ⊗ with c: (a²/b)⊗c = ( (a²/b)² ) / c = a⁴ / (b² c).\n\nNow, the second expression: a⊗(b⊗c). First compute b⊗c = b²/c.\n\nThen, a⊗(b²/c) = a² / (b²/c) = a² * (c / b²) = (a² c) / b².\n\nTherefore, the difference between the two expressions is:\n\n(a⁴ / (b² c)) - (a² c / b²) = (a⁴ - a² c²) / (b² c) = a² (a² - c²) / (b² c).\n\nHmm, factoring that, it's a² (a - c)(a + c) / (b² c).\n\nBut in our specific problem, a = 1, b = 2, c = 3. Plugging those values in:\n\n1² (1 - 3)(1 + 3) / (2² * 3) = 1 * (-2)(4) / (4 * 3) = (-8) / 12 = -2/3. Same result.

So, ( (1/2)² ) / 3 = (1/4) / 3 = 1/12. So, (1⊗2)⊗3 equals 1/12. Alright, that's the first part. Now let's compute the second part: 1⊗(2⊗3). Again, starting with the innermost operation, which is 2⊗3. Applying the definition: a is 2 and b is 3. So, 2² / 3 = 4/3. Therefore, 2⊗3 equals 4/3. Now, we need to compute 1⊗(4/3). Here, a is 1 and b is 4/3. Using the operation definition: 1² / (4/3) = 1 / (4/3) = 3/4. So, 1⊗(2⊗3) equals 3/4. Now, the problem asks for the difference between the two results: [(1⊗2)⊗3] - [1⊗(2⊗3)] = (1/12) - (3/4). To subtract these fractions, they need a common denominator. The denominators are 12 and 4, so 12 is the common denominator. Converting 3/4 to twelfths: 3/4 = 9/12. So, 1/12 - 9/12 = (1 - 9)/12 = -8/12. Simplifying that fraction by dividing numerator and denominator by 4: -8/12 = -2/3. Hmm, looking at the answer choices, option A is -2/3. So, is that the answer?

Then, a⊗(b²/c) = a² / (b²/c) = a² * (c / b²) = (a² c) / b². Therefore, the difference between the two expressions is: (a⁴ / (b² c)) - (a² c / b²) = (a⁴ - a² c²) / (b² c) = a² (a² - c²) / (b² c). Hmm, factoring that, it's a² (a - c)(a + c) / (b² c). But in our specific problem, a = 1, b = 2, c = 3. Plugging those values in: 1² (1 - 3)(1 + 3) / (2² * 3) = 1 * (-2)(4) / (4 * 3) = (-8) / 12 = -2/3. Same result. So that confirms the answer is indeed -2/3.

So Doug has a square window made up of 8 equal-sized panes of glass. Each pane has a height to width ratio of 5:2. There are borders around and between the panes that are 2 inches wide. The question is asking for the side length of the square window in inches. The answer choices are from 26 to 34, so it's a matter of working through the dimensions step by step.\n\nFirst, I need to visualize the window. The Asymptote code shows something with multiple panes and borders. Since it's a square window, the total height and width should be equal. The problem mentions 8 panes, so I need to figure out how they're arranged. Since 8 can be divided in different ways (like 2x4, 4x2, or maybe even 1x8 but that's less likely for a square window), but given that it's a square, the arrangement should probably be such that the number of panes vertically and horizontally would contribute to making the total height and width equal.\n\nWait, the answer choices are all even numbers, and the borders are 2 inches, which might be a clue. Let me think. If the ratio of height to width for each pane is 5:2, then each pane's height is 5x and width is 2x for some x. The borders around and between the panes are 2 inches. So maybe I need to calculate the total height and total width of the window by considering the panes and the borders.\n\nBut first, how are the 8 panes arranged? Let me check the Asymptote code. The Asymptote code is given, but I can't see the image. However, the code has several filled rectangles. The coordinates in the Asymptote code might give a clue. Let me parse the Asymptote code:\n\n- The first fill command is from (0,0) to (2,0) to (2,26) to (0,26). So that's a vertical border on the left, 2 units wide (from x=0 to x=2) and spans the entire height (from y=0 to y=26). Wait, but in the problem statement, the borders are 2 inches wide. Hmm, but in the Asymptote code, the coordinates go up to 26? Wait, but the answer choices include 26 as an option. Maybe the Asymptote code is illustrative but not to scale. Because the answer is one of the options, maybe 26 is the side length? But let me not jump to conclusions.\n\nLooking at the Asymptote code:\n\n- There are five vertical panes? Let's see:\n\n1. (0,0)--(2,0)--(2,26)--(0,26): This is a vertical border on the left, 2 units wide, 26 units tall.\n\n2. (6,0)--(8,0)--(8,26)--(6,26): Another vertical border from x=6 to x=8, spanning the full height. Similarly, there's one at (12,0) to (14,0), (18,0) to (20,0), (24,0) to (26,0). So between these vertical borders, there are spaces where the panes might be.\n\nSimilarly, the horizontal borders:\n\n- (0,0)--(26,0)--(26,2)--(0,2): This is a horizontal border at the bottom, 2 inches tall, spanning the entire width.\n\n- (0,12)--(26,12)--(26,14)--(0,14): Another horizontal border in the middle, 2 inches tall.\n\n- (0,24)--(26,24)--(26,26)--(0,26): A horizontal border at the top, 2 inches tall.\n\nSo from the Asymptote code, the window is 26 units wide and 26 units tall. But the answer choices include 26, which is option A. But the problem says that the borders are 2 inches wide, so maybe in the Asymptote code, each unit is 1 inch. But if that's the case, then the side length is 26 inches. But the problem says the ratio of height to width for each pane is 5:2, so maybe that conflicts?\n\nWait, perhaps the Asymptote code is just a diagram, and the coordinates are not to scale. Because if each pane has a ratio of 5:2, then the panes would be taller than they are wide. But in the Asymptote code, the vertical panes (if they are the glass panes) are 2 units wide (from x=2 to x=6 is 4 units, but maybe that's a pane? Wait, no. Let me parse the Asymptote code again.\n\nWait, the filled regions are the borders, right? Because the problem says \"borders around and between the panes are 2 inches wide\". So the filled gray areas are the borders. Therefore, the panes are the white spaces between the borders.\n\nLooking at the vertical borders: the first vertical border is from x=0 to x=2 (2 units wide), then the next vertical border is from x=6 to x=8. So between x=2 and x=6, which is 4 units, there might be a pane. Similarly, between x=8 and x=12, another pane, then between x=14 and x=18, x=20 and x=24, and x=24 to x=26? Wait, x=24 to x=26 is another vertical border? Wait, the last vertical border is from (24,0) to (26,0) to (26,26) to (24,26). So that's the rightmost border, 2 units wide. So between the vertical borders, the panes are placed. Let's count the panes horizontally.\n\nFrom the vertical borders:\n\n- Left border: 0-2\n\n- Then a pane from 2-6 (width 4)\n\n- Then border 6-8\n\n- Then a pane from 8-12 (width 4)\n\n- Then border 12-14\n\n- Pane 14-18 (width 4)\n\n- Border 18-20\n\n- Pane 20-24 (width 4)\n\n- Border 24-26 (width 2)\n\nSo there are 4 panes horizontally, each 4 units wide. Wait, but the problem states 8 panes. So vertically, maybe there are two rows?\n\nLooking at the horizontal borders:\n\n- Bottom border: 0-2 in y-axis.\n\n- Then a horizontal border from y=12-14.\n\n- Top border from y=24-26.\n\nSo the panes would be between the horizontal borders:\n\n- Between y=2 and y=12 (height 10)\n\n- Between y=14 and y=24 (height 10)\n\nSo two rows of panes vertically, each 10 units tall. So each pane is 10 units tall and 4 units wide? But the problem states the ratio of height to width for each pane is 5:2. Let's check 10:4 simplifies to 5:2. Yes, so 10/4 = 5/2, so that's consistent. So if each pane is 10 units tall and 4 units wide, then with the ratio 5:2 (height to width), each unit is 2.5 inches in height and 2 inches in width? Wait, no, hold on. Wait, in the Asymptote code, the panes have height 10 and width 4, which is a ratio of 10:4 = 5:2, so that matches. But the problem says the borders are 2 inches wide. But in the Asymptote code, the borders are 2 units wide. So if each unit in the Asymptote code corresponds to 1 inch, then the borders are 2 inches, which matches. But then the panes are 4 units wide (4 inches) and 10 units tall (10 inches), which would give the ratio 10:4 = 5:2. So that works. Then the total size of the window would be 26 units in the Asymptote code, which would be 26 inches, corresponding to option A. But the answer is 26? But let's verify again because the answer choices include 34, which is larger.\n\nWait, but maybe my assumption that each unit in the Asymptote code is 1 inch is incorrect. Maybe the panes are not 10 and 4 in actual inches, but the ratio is 5:2. Let's approach this step by step without relying on the Asymptote code's coordinates.\n\nSo the window is square, so total height = total width. There are 8 panes. Let's figure out the arrangement. 8 panes could be arranged in 2 rows of 4 panes each, which would make sense for a square window. Because 2 rows by 4 columns would make the window's aspect ratio closer to square if each pane's height to width ratio is 5:2. Alternatively, 4 rows of 2 panes, but that might make the window taller than wide. Let's check both possibilities.\n\nFirst, assume the panes are arranged in 2 rows and 4 columns. Then, vertically, there are 2 panes stacked, and horizontally, 4 panes side by side. Let's calculate the total height and width.\n\nEach pane has height h and width w, with h/w = 5/2. So h = (5/2)w.\n\nIn the vertical direction: There are 2 panes, each of height h. Between them, there is a border. Also, there are borders at the top and bottom. So total vertical height = bottom border + 2 panes + 1 border between them + top border. Since borders are 2 inches wide.\n\nSimilarly, in the horizontal direction: 4 panes, each of width w, with borders between them and on the sides. So total horizontal width = left border + 4 panes + 3 borders between them + right border.\n\nSince the window is square, total height = total width.\n\nLet me write equations.\n\nVertical direction:\n\nTotal height = 2 (bottom border) + 2h + 12 (border between panes) + 2 (top border)\n\nWait, actually, borders are 2 inches wide. So the vertical borders (the horizontal ones?) Wait, in the vertical direction (height), the borders are horizontal. The vertical direction's total height would be:\n\nTop border (2 inches) + bottom border (2 inches) + space taken by the panes and the borders between them. Since there are 2 panes vertically, there is 1 border between them. Each pane has height h. So total vertical height:\n\n= 2 (top border) + 2 (bottom border) + 2h + 1(2) (the border between the two panes)\n\nWait, no. Wait, if you have two panes stacked vertically, then you have:\n\nStarting from the bottom: bottom border (2 inches), then a pane (h), then a border (2 inches), then another pane (h), then top border (2 inches). So total height:\n\n= 2 + h + 2 + h + 2 = 23 + 2h = 6 + 2h.\n\nSimilarly, in the horizontal direction, 4 panes. So starting from the left: left border (2 inches), then pane (w), then border (2 inches), next pane (w), border, pane, border, pane, right border. So number of borders between panes horizontally is 3. So total width:\n\n= 2 (left) + 4w + 32 (borders) + 2 (right) = 2 + 4w + 6 + 2 = 10 + 4w.\n\nSince total height = total width:\n\n6 + 2h = 10 + 4w.\n\nBut h = (5/2)w, so substitute:\n\n6 + 2(5/2)w = 10 + 4w\n\nSimplify:\n\n6 + 5w = 10 + 4w\n\nSubtract 4w from both sides:\n\n6 + w = 10\n\nSubtract 6:\n\nw = 4 inches.\n\nThen h = (5/2)4 = 10 inches.\n\nThen total height = 6 + 2h = 6 + 20 = 26 inches.\n\nTotal width = 10 + 4w = 10 + 16 = 26 inches. So that gives a square of 26 inches, which is option A.\n\nBut let me check if the arrangement is indeed 2 rows by 4 columns. The problem says 8 panes. If arranged as 4 rows by 2 columns, would that give a different result? Let's verify.\n\nIf arranged in 4 rows and 2 columns:\n\nVertical direction (height):\n\nTop border (2) + 4 panes (each h) + 3 borders (each 2) + bottom border (2). So total height:\n\n= 2 + 4h + 32 + 2 = 2 + 4h + 6 + 2 = 10 + 4h.\n\nHorizontal direction (width):\n\nLeft border (2) + 2 panes (each w) + 1 border (2) + right border (2). Total width:\n\n= 2 + 2w + 2 + 2 = 6 + 2w.\n\nSet equal:\n\n10 + 4h = 6 + 2w.\n\nBut h = (5/2)w, so substitute:\n\n10 + 4(5/2)w = 6 + 2w\n\n10 + 10w = 6 + 2w\n\n10 - 6 = 2w -10w\n\n4 = -8w\n\nWhich gives w = -0.5, which is impossible. So that arrangement can't be. Therefore, the panes must be arranged in 2 rows by 4 columns, leading to total side length 26 inches, which is answer choice A.\n\nWait, but the Asymptote code's coordinates go up to 26, which seems to correspond to this answer. So 26 is the answer. But let me check again to make sure I didn't make a mistake.\n\nGiven h = 10 inches, w = 4 inches. Each pane is 10 inches tall and 4 inches wide. The ratio 10:4 is 5:2, which matches. The borders are 2 inches. The vertical total is 2 (bottom) + 10 + 2 + 10 + 2 (top) = 26. The horizontal total is 2 (left) + 44 (panes) + 32 (borders between) + 2 (right) = 2 + 16 + 6 + 2 = 26. Perfect, that's consistent. So the side length is 26 inches, which is option A.\n\nBut the answer given in the choices is A) 26, which seems right. But wait, the Asymptote code has coordinates going up to 26, but in the problem, the borders are 2 inches. If the Asymptote code is using units where each unit is 1 inch, then the total would be 26 inches. But just to be thorough, let me check once more.\n\nAlternative approach: Let's denote the width of each pane as 2k and the height as 5k (since the ratio is 5:2). Then, for the horizontal direction (assuming 4 panes per row):\n\nTotal width = left border + 4(pane width) + 3(border) + right border\n\n= 2 + 4(2k) + 32 + 2\n\n= 2 + 8k + 6 + 2\n\n= 10 + 8k\n\nTotal height = bottom border + 2(pane height) + 1(border) + top border\n\n= 2 + 2(5k) + 2 + 2\n\n= 2 + 10k + 2 + 2\n\n= 6 + 10k\n\nSince it's a square, 10 + 8k = 6 + 10k\n\nSolving:\n\n10 - 6 = 10k - 8k\n\n4 = 2k => k = 2\n\nTherefore, pane width = 2k = 4 inches, pane height = 5k = 10 inches.\n\nTotal width = 10 + 8k = 10 + 16 = 26 inches.\n\nTotal height = 6 + 10k = 6 + 20 = 26 inches. So yes, same result. Therefore, the answer is 26, option A.\n\nBut wait, the answer choices given are up to 34, and the Asymptote code might have coordinates up to 26, but maybe the actual answer is different? Wait, but according to the calculations, it's 26. Let me check if there's an alternative interpretation.\n\nWait, the problem says \"the borders around and between the panes are 2 inches wide\". So maybe the borders include both the frame around the window and the spaces between panes. In the calculation above, we considered left, right, top, bottom borders as 2 inches each, and between the panes also 2 inches. So in the horizontal direction, for 4 panes, there are 3 borders between them, each 2 inches, plus left and right borders. Similarly, vertically, 2 panes have 1 border between them, plus top and bottom borders.\n\nYes, that's exactly how we calculated. So everything adds up to 26. Therefore, the answer should be 26, which is option A. Therefore, I think the correct answer is A) 26.\n\nFinal Answer\n\\boxed{A}\n\n<\|end_of_thought\|>\n\n<\|begin_of_solution\|>\n\nDoug constructs a square window using 8 equal-size panes of glass, with a height to width ratio of 5:2 for each pane. The borders around and between the panes are 2 inches wide. We need to determine the side length of the square window.\n\n1. Arrangement of Panes: The panes are arranged in 2 rows and 4 columns. This arrangement ensures the window is square.\n2. Dimensions of Each Pane: Let the width of each pane be \\(2k\\) and the height be \\(5k\\). The ratio of height to width is \\(5:2\\).\n3.

So Doug has a square window made up of 8 equal-sized panes of glass. Each pane has a height to width ratio of 5:2. There are borders around and between the panes that are 2 inches wide. The question is asking for the side length of the square window in inches. The answer choices are from 26 to 34, so it's a matter of working through the dimensions step by step. First, I need to visualize the window. The Asymptote code shows something with multiple panes and borders. Since it's a square window, the total height and width should be equal. The problem mentions 8 panes, so I need to figure out how they're arranged. Since 8 can be divided in different ways (like 2x4, 4x2, or maybe even 1x8 but that's less likely for a square window), but given that it's a square, the arrangement should probably be such that the number of panes vertically and horizontally would contribute to making the total height and width equal. Wait, the answer choices are all even numbers, and the borders are 2 inches, which might be a clue. Let me think. If the ratio of height to width for each pane is 5:2, then each pane's height is 5x and width is 2x for some x. The borders around and between the panes are 2 inches. So maybe I need to calculate the total height and total width of the window by considering the panes and the borders. But first, how are the 8 panes arranged? Let me check the Asymptote code. The Asymptote code is given, but I can't see the image. However, the code has several filled rectangles. The coordinates in the Asymptote code might give a clue. Let me parse the Asymptote code: - The first fill command is from (0,0) to (2,0) to (2,26) to (0,26). So that's a vertical border on the left, 2 units wide (from x=0 to x=2) and spans the entire height (from y=0 to y=26). Wait, but in the problem statement, the borders are 2 inches wide. Hmm, but in the Asymptote code, the coordinates go up to 26? Wait, but the answer choices include 26 as an option. Maybe the Asymptote code is illustrative but not to scale. Because the answer is one of the options, maybe 26 is the side length? But let me not jump to conclusions. Looking at the Asymptote code: - There are five vertical panes? Let's see: 1. (0,0)--(2,0)--(2,26)--(0,26): This is a vertical border on the left, 2 units wide, 26 units tall. 2. (6,0)--(8,0)--(8,26)--(6,26): Another vertical border from x=6 to x=8, spanning the full height. Similarly, there's one at (12,0) to (14,0), (18,0) to (20,0), (24,0) to (26,0). So between these vertical borders, there are spaces where the panes might be. Similarly, the horizontal borders: - (0,0)--(26,0)--(26,2)--(0,2): This is a horizontal border at the bottom, 2 inches tall, spanning the entire width. - (0,12)--(26,12)--(26,14)--(0,14): Another horizontal border in the middle, 2 inches tall. - (0,24)--(26,24)--(26,26)--(0,26): A horizontal border at the top, 2 inches tall. So from the Asymptote code, the window is 26 units wide and 26 units tall. But the answer choices include 26, which is option A. But the problem says that the borders are 2 inches wide, so maybe in the Asymptote code, each unit is 1 inch. But if that's the case, then the side length is 26 inches. But the problem says the ratio of height to width for each pane is 5:2, so maybe that conflicts? Wait, perhaps the Asymptote code is just a diagram, and the coordinates are not to scale. Because if each pane has a ratio of 5:2, then the panes would be taller than they are wide. But in the Asymptote code, the vertical panes (if they are the glass panes) are 2 units wide (from x=2 to x=6 is 4 units, but maybe that's a pane? Wait, no. Let me parse the Asymptote code again. Wait, the filled regions are the borders, right? Because the problem says "borders around and between the panes are 2 inches wide". So the filled gray areas are the borders. Therefore, the panes are the white spaces between the borders. Looking at the vertical borders: the first vertical border is from x=0 to x=2 (2 units wide), then the next vertical border is from x=6 to x=8. So between x=2 and x=6, which is 4 units, there might be a pane. Similarly, between x=8 and x=12, another pane, then between x=14 and x=18, x=20 and x=24, and x=24 to x=26? Wait, x=24 to x=26 is another vertical border? Wait, the last vertical border is from (24,0) to (26,0) to (26,26) to (24,26). So that's the rightmost border, 2 units wide. So between the vertical borders, the panes are placed. Let's count the panes horizontally. From the vertical borders: - Left border: 0-2 - Then a pane from 2-6 (width 4) - Then border 6-8 - Then a pane from 8-12 (width 4) - Then border 12-14 - Pane 14-18 (width 4) - Border 18-20 - Pane 20-24 (width 4) - Border 24-26 (width 2) So there are 4 panes horizontally, each 4 units wide. Wait, but the problem states 8 panes. So vertically, maybe there are two rows? Looking at the horizontal borders: - Bottom border: 0-2 in y-axis. - Then a horizontal border from y=12-14. - Top border from y=24-26. So the panes would be between the horizontal borders: - Between y=2 and y=12 (height 10) - Between y=14 and y=24 (height 10) So two rows of panes vertically, each 10 units tall. So each pane is 10 units tall and 4 units wide? But the problem states the ratio of height to width for each pane is 5:2. Let's check 10:4 simplifies to 5:2. Yes, so 10/4 = 5/2, so that's consistent. So if each pane is 10 units tall and 4 units wide, then with the ratio 5:2 (height to width), each unit is 2.5 inches in height and 2 inches in width? Wait, no, hold on. Wait, in the Asymptote code, the panes have height 10 and width 4, which is a ratio of 10:4 = 5:2, so that matches. But the problem says the borders are 2 inches wide. But in the Asymptote code, the borders are 2 units wide. So if each unit in the Asymptote code corresponds to 1 inch, then the borders are 2 inches, which matches. But then the panes are 4 units wide (4 inches) and 10 units tall (10 inches), which would give the ratio 10:4 = 5:2. So that works. Then the total size of the window would be 26 units in the Asymptote code, which would be 26 inches, corresponding to option A. But the answer is 26? But let's verify again because the answer choices include 34, which is larger. Wait, but maybe my assumption that each unit in the Asymptote code is 1 inch is incorrect. Maybe the panes are not 10 and 4 in actual inches, but the ratio is 5:2. Let's approach this step by step without relying on the Asymptote code's coordinates. So the window is square, so total height = total width. There are 8 panes. Let's figure out the arrangement. 8 panes could be arranged in 2 rows of 4 panes each, which would make sense for a square window. Because 2 rows by 4 columns would make the window's aspect ratio closer to square if each pane's height to width ratio is 5:2. Alternatively, 4 rows of 2 panes, but that might make the window taller than wide. Let's check both possibilities. First, assume the panes are arranged in 2 rows and 4 columns. Then, vertically, there are 2 panes stacked, and horizontally, 4 panes side by side. Let's calculate the total height and width. Each pane has height h and width w, with h/w = 5/2. So h = (5/2)w. In the vertical direction: There are 2 panes, each of height h. Between them, there is a border. Also, there are borders at the top and bottom. So total vertical height = bottom border + 2 panes + 1 border between them + top border. Since borders are 2 inches wide. Similarly, in the horizontal direction: 4 panes, each of width w, with borders between them and on the sides. So total horizontal width = left border + 4 panes + 3 borders between them + right border. Since the window is square, total height = total width. Let me write equations. Vertical direction: Total height = 2 (bottom border) + 2h + 12 (border between panes) + 2 (top border) Wait, actually, borders are 2 inches wide. So the vertical borders (the horizontal ones?) Wait, in the vertical direction (height), the borders are horizontal. The vertical direction's total height would be: Top border (2 inches) + bottom border (2 inches) + space taken by the panes and the borders between them. Since there are 2 panes vertically, there is 1 border between them. Each pane has height h. So total vertical height: = 2 (top border) + 2 (bottom border) + 2h + 1(2) (the border between the two panes) Wait, no. Wait, if you have two panes stacked vertically, then you have: Starting from the bottom: bottom border (2 inches), then a pane (h), then a border (2 inches), then another pane (h), then top border (2 inches). So total height: = 2 + h + 2 + h + 2 = 23 + 2h = 6 + 2h. Similarly, in the horizontal direction, 4 panes. So starting from the left: left border (2 inches), then pane (w), then border (2 inches), next pane (w), border, pane, border, pane, right border. So number of borders between panes horizontally is 3. So total width: = 2 (left) + 4w + 32 (borders) + 2 (right) = 2 + 4w + 6 + 2 = 10 + 4w. Since total height = total width: 6 + 2h = 10 + 4w. But h = (5/2)w, so substitute: 6 + 2(5/2)w = 10 + 4w Simplify: 6 + 5w = 10 + 4w Subtract 4w from both sides: 6 + w = 10 Subtract 6: w = 4 inches. Then h = (5/2)4 = 10 inches. Then total height = 6 + 2h = 6 + 20 = 26 inches. Total width = 10 + 4w = 10 + 16 = 26 inches. So that gives a square of 26 inches, which is option A. But let me check if the arrangement is indeed 2 rows by 4 columns. The problem says 8 panes. If arranged as 4 rows by 2 columns, would that give a different result? Let's verify. If arranged in 4 rows and 2 columns: Vertical direction (height): Top border (2) + 4 panes (each h) + 3 borders (each 2) + bottom border (2). So total height: = 2 + 4h + 32 + 2 = 2 + 4h + 6 + 2 = 10 + 4h. Horizontal direction (width): Left border (2) + 2 panes (each w) + 1 border (2) + right border (2). Total width: = 2 + 2w + 2 + 2 = 6 + 2w. Set equal: 10 + 4h = 6 + 2w. But h = (5/2)w, so substitute: 10 + 4(5/2)w = 6 + 2w 10 + 10w = 6 + 2w 10 - 6 = 2w -10w 4 = -8w Which gives w = -0.5, which is impossible. So that arrangement can't be. Therefore, the panes must be arranged in 2 rows by 4 columns, leading to total side length 26 inches, which is answer choice A. Wait, but the Asymptote code's coordinates go up to 26, which seems to correspond to this answer. So 26 is the answer. But let me check again to make sure I didn't make a mistake. Given h = 10 inches, w = 4 inches. Each pane is 10 inches tall and 4 inches wide. The ratio 10:4 is 5:2, which matches. The borders are 2 inches. The vertical total is 2 (bottom) + 10 + 2 + 10 + 2 (top) = 26. The horizontal total is 2 (left) + 44 (panes) + 32 (borders between) + 2 (right) = 2 + 16 + 6 + 2 = 26. Perfect, that's consistent. So the side length is 26 inches, which is option A. But the answer given in the choices is A) 26, which seems right. But wait, the Asymptote code has coordinates going up to 26, but in the problem, the borders are 2 inches. If the Asymptote code is using units where each unit is 1 inch, then the total would be 26 inches. But just to be thorough, let me check once more. Alternative approach: Let's denote the width of each pane as 2k and the height as 5k (since the ratio is 5:2). Then, for the horizontal direction (assuming 4 panes per row): Total width = left border + 4(pane width) + 3(border) + right border = 2 + 4(2k) + 32 + 2 = 2 + 8k + 6 + 2 = 10 + 8k Total height = bottom border + 2(pane height) + 1(border) + top border = 2 + 2(5k) + 2 + 2 = 2 + 10k + 2 + 2 = 6 + 10k Since it's a square, 10 + 8k = 6 + 10k Solving: 10 - 6 = 10k - 8k 4 = 2k => k = 2 Therefore, pane width = 2k = 4 inches, pane height = 5k = 10 inches. Total width = 10 + 8k = 10 + 16 = 26 inches. Total height = 6 + 10k = 6 + 20 = 26 inches. So yes, same result. Therefore, the answer is 26, option A. But wait, the answer choices given are up to 34, and the Asymptote code might have coordinates up to 26, but maybe the actual answer is different? Wait, but according to the calculations, it's 26. Let me check if there's an alternative interpretation. Wait, the problem says "the borders around and between the panes are 2 inches wide".

Then the total size of the window would be 26 units in the Asymptote code, which would be 26 inches, corresponding to option A. But the answer is 26? Given h = 10 inches, w = 4 inches. Each pane is 10 inches tall and 4 inches wide. The ratio 10:4 is 5:2, which matches. The borders are 2 inches. The vertical total is 2 (bottom) + 10 + 2 + 10 + 2 (top) = 26. The horizontal total is 2 (left) + 44 (panes) + 32 (borders between) + 2 (right) = 2 + 16 + 6 + 2 = 26. Perfect, that's consistent. So the side length is 26 inches, which is option A.
