Question

Find the area of the trapezoid. the top is 15.8 yards, the inside is 11.7 yards, and the bottom is 21.8 yards.

A.127.53yd^2

B.92.43yd^2

D.219.96yd^2

C.439.92yd^2

Answer 1

The answer is D. 219.96yd^2

Answer 2

The area of a trapezoid is 1/2(b1+b2)h
In this problem:

b1=15.8
b2=21.8
h=11.7

If we plug the numbers into the formula, we get:

A = 1/2(15.8+21.8)(11.7)
A = 1/2(344.44)(11.7)
A = 219.96 yards²
