Question

The courtyard behind Jennie’s house is shaped like a trapezoid the bases measures 8 meters and 11 meters the height of the trapezoid is 12 meters what is the area of the courtyard

Answer 1

A = 114 m²

Explanation:

The formula for area of a trapezoid is

A = (1/2)(B + b)h where B is the bottom base, b is the top base, and h is the height.

We are given B = 11, b = 8, and h = 12, plug those values in and simplify

A = (1/2)(11 + 8)(12)

A = (1/2)(19)(12)

A = (19)(6) (half of 12 is 6)

A = 114 m²
