Hi there!
First, let's find the area of the center rectangles:
1(8 x 9) + 1(15 x 9) + 1(17 x 9) = 360
Next, we'll find the area of the triangles:
2(0.5(15 x 8)) = 120
Lastly, we'll add the two areas together:
360 + 120 = 480
Therefore, the answer is 480in^2. The correct option is the second option.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
