A farmer grows watermelons in a trapezoid-shaped section of his farmland. The top base of the trapezoid is 100 ft long. The bottom base of the trapezoid is 112 ft long. The height is 13 ft. What is the area in which the farmer grows watermelons? Enter your answer in the box.

Respuesta :

The answer is  1,378 ft².

The area of the trapezoid is: A = (a+b)/2 * h, where a and b are bases and h is height.

We know that:
a = 100 ft
b = 112 ft
h = 13 ft

Calculate the area:
A = (a+b)/2 * h
A = (100 + 112)/2 * 13
A = 212/2 * 13
A = 106 * 13
A = 1,378 ft²
