Question

A parking lot in a shape of a trapezoid has an area of 12,052.1 square meters.the lean the of one base is 82.4 meters and the length of the other base is 108.6 meters.what is the height of the parking lot?

Answer 1

126.2 meters

Explanation:

A trapezoid's area is found using the formula A = 1/2 (a+b)h where a and b are the two bases. Substitute A = 12,052.1, a = 82.4 and b=108.6. Then solve for h.

A = 0.5(a+b)h

12,052.1 = 0.5(82.4 + 108.6)*h

12,052.1 = 0.5(191)h

12,052.1 = 95.5h

126.2 = h
