Number 7 i can not figure out for anything. i keep getting the answer of 103.1 but the back of the book says its 88.1 ft squared. can someone show me how to get this answer?

You have a semicircle attached to a trapezium

Area of semicircle = 1/2 Pi r^2 = 1/2 + pi * 4^2 = 25.13 ( note r = 1/2 * 8 = 4)

Area of the trapezium = h/2 ( sum of 2 parallel sides) = 1/2 * 6 * (13 + 8)

= 63

Total area = 63 + 25.13 = 88.1 to nearest tenth
