Explanation:

Step1: Identify length and width of Rectangle 2

Length of Rectangle 2 is 15 m, width is 12 m? Wait, no, wait. Wait, looking at the diagram, Rectangle 2: the vertical side is 15 m, and the horizontal side? Wait, the first rectangle (Rectangle 1) is 6m x 6m. Then Rectangle 2: let's check the dimensions. Wait, the problem says "Area = length × width". For Rectangle 2, from the diagram, the length is 15 m and the width? Wait, the top side of Rectangle 2 is 12 m? Wait, no, maybe I misread. Wait, the blue rectangle (Rectangle 1) is 6m (height) and 6m (width). Then the green rectangle (Rectangle 2) has height 15 m and width? Wait, the total horizontal length at the bottom is 15 m, but Rectangle 3 is 9m x 6m. Wait, maybe Rectangle 2's width is 12 - 6? No, wait, the top of Rectangle 2 is 12 m? Wait, no, let's re-express. Wait, the formula for the area of a rectangle is \( A = l \times w \), where \( l \) is length and \( w \) is width.

Looking at Rectangle 2: the height (length) is 15 m, and the width? Wait, the horizontal side: the first rectangle (Rectangle 1) is 6m wide, and the total top length is 12 m? Wait, no, maybe the width of Rectangle 2 is 12 - 6? No, that doesn't make sense. Wait, maybe the width of Rectangle 2 is 12 m? Wait, no, the diagram shows Rectangle 2 with height 15 m and width? Wait, maybe I made a mistake. Wait, the problem says "Find the area of each rectangle. What is the area of rectangle 2? Area = length × width. Rectangle 1: 36 m² (which is 6×6, correct). Then Rectangle 2: let's see, the vertical side is 15 m, and the horizontal side: from the top, it's 12 m? Wait, no, maybe the width of Rectangle 2 is 12 - 6? No, that's 6, but Rectangle 1 is 6x6. Wait, maybe the width of Rectangle 2 is 12 m? Wait, no, the diagram: the green rectangle (Rectangle 2) has height 15 m and width? Wait, the total horizontal length at the top is 12 m, but Rectangle 1 is 6m wide, so maybe Rectangle 2's width is 12 - 6 = 6? No, that can't be. Wait, maybe the width of Rectangle 2 is 12 m? Wait, no, let's check the numbers. Wait, the problem is to find the area of Rectangle 2. Let's look at the dimensions. The height of Rectangle 2 is 15 m, and the width? Wait, the horizontal side: the first rectangle (Rectangle 1) is 6m (width) and 6m (height). Then Rectangle 2: the vertical side is 15 m, and the horizontal side: from the top, it's 12 m? Wait, no, maybe the width of Rectangle 2 is 12 m? Wait, no, the diagram shows that the top of Rectangle 2 is 12 m, and the height is 15 m? Wait, no, that would make the area 12×15=180, but that seems too big. Wait, maybe I misread the dimensions. Wait, the blue rectangle (Rectangle 1) is 6m (height) and 6m (width). Then the green rectangle (Rectangle 2) has height 15 m and width? Wait, the horizontal length from the left to the right of Rectangle 2: the total top length is 12 m, but Rectangle 1 is 6m wide, so maybe Rectangle 2's width is 12 - 6 = 6? No, that's 6, but then area would be 6×15=90. Wait, but maybe the width is 12 m? Wait, no, let's check the problem again.

Wait, the problem says "Find the area of each rectangle. What is the area of rectangle 2? Area = length × width. Rectangle 1: 36 m² (6×6). Then Rectangle 2: let's see, the vertical side is 15 m, and the horizontal side: the top of Rectangle 2 is 12 m? Wait, maybe the width of Rectangle 2 is 12 m? Wait, no, the diagram: the green rectangle (Rectangle 2) is between Rectangle 1 and Rectangle 3. Rectangle 3 is 9m (width) and 6m (height). The total horizontal length at the bottom is 15 m (6 + 9? No, 6 + 9 = 15? Wait, 6 (Rectangle 1's width) + 9 (Rectangle 3's width) = 15? Yes! So Rectangle 2's width is 15 - 6 - 9? No, that can't be. Wait, no, the top length is 12 m. Wait, maybe the width of Rectangle 2 is 12 - 6 = 6? No, this is confusing. Wait, let's look at the formula: Area = length × width. For Rectangle 2, the length is 15 m (vertical) and the width is 12 - 6 = 6? No, that's 6, but then 15×6=90. Wait, but maybe the width is 12 m? Wait, no, the first rectangle is 6m wide, so the remaining width for Rectangle 2 is 12 - 6 = 6? Wait, the top length is 12 m, so Rectangle 1 is 6m wide, so Rectangle 2's width is 12 - 6 = 6 m? Then height is 15 m? So area is 15×6=90? Wait, but let's check the numbers again.

Wait, the problem is to find the area of Rectangle 2. Let's list the dimensions:

- Rectangle 1: 6m (length) × 6m (width) = 36 m² (correct, as given).

- Rectangle 2: Let's see, the vertical side (length) is 15 m, and the horizontal side (width) is 12 - 6 = 6 m? Wait, no, 12 m is the top length, and Rectangle 1 is 6m wide, so Rectangle 2's width is 12 - 6 = 6 m? Then area is 15 × 6 = 90 m²? Wait, but maybe the width is 12 m? Wait, no, the diagram shows that Rectangle 1 is 6m wide, so the remaining width for Rectangle 2 is 12 - 6 = 6 m. Then height is 15 m. So area is 15 × 6 = 90. Wait, but let's check the bottom length: 15 m (total bottom length) = 6 m (Rectangle 1's width) + 9 m (Rectangle 3's width)? No, 6 + 9 = 15, so that's correct. So Rectangle 2's width is 12 - 6 = 6 m? Wait, no, the top length is 12 m, bottom is 15 m. Wait, maybe I'm mixing up length and width. Maybe the length of Rectangle 2 is 15 m (vertical) and the width is 12 m (horizontal)? But then 15×12=180. But that seems too big. Wait, the problem says "Area = length × width". Let's check the given Rectangle 1: 6×6=36, correct. Then Rectangle 2: let's see, the height is 15 m, and the width is 12 - 6 = 6 m? No, 12 - 6 is 6, but 6×15=90. Alternatively, maybe the width is 12 m and height is 15 m? Then 12×15=180. Wait, but the bottom length is 15 m, which is 6 + 9, so Rectangle 2's width should be 15 - 6 - 9 = 0? No, that can't be. Wait, maybe the diagram is such that Rectangle 2 has length 15 m and width 12 - 6 = 6 m? Wait, I think I made a mistake. Let's re-express:

Wait, the top of the figure has a length of 12 m, with Rectangle 1 (6m x 6m) on the left, and Rectangle 2 (green) next to it. Then the bottom has a length of 15 m, with Rectangle 3 (9m x 6m) on the right, and Rectangle 2 (green) in the middle. So the width of Rectangle 2 is 15 - 9 = 6 m? Wait, 15 - 9 = 6. Then the height of Rectangle 2 is 15 m? Wait, no, the height of Rectangle 1 and Rectangle 3 is 6 m, so maybe Rectangle 2's height is 15 m, and width is 6 m? Then area is 15×6=90. Yes, that makes sense. So:

Step1: Determine length and width of Rectangle 2

Length (\( l \)) of Rectangle 2 = 15 m (vertical side)
Width (\( w \)) of Rectangle 2 = 15 - 9 = 6 m (horizontal side, since total bottom length is 15 m and Rectangle 3 is 9 m wide)

Step2: Calculate area using \( A = l \times w \)

\( A = 15 \times 6 \)
\( A = 90 \)

Answer:

90
