Answer:
560 ft squared
Explanation:
Square side: 10 x 10 = 100
Rectangle Side: 14 x 10 = 140
2 (100 + 140) = 480 ft squared is the base
Triangle Roof: 9 x 14 = 126
126 x 2 = 152
Front and back of triangle: 10 x 8 = 80 ft squared
Answer 480 + 80 = 560 ft squared
You would have to divide by 2 if there was 1 front triangle and no back because a triangle is half of a square and you multiply how a square does and divide by 2.
Hope that helps :)
