Given:
Given that the bases of the trapezoid are 20 ft and 16 feet.
The height of the trapezoid is 24 ft.
We need to determine the area of the trapezoid.
Area of the trapezoid:
The area of the trapezoid can be determined using the formula,

where a and b are the bases of the trapezoid and h is the height of the trapezoid.
Substituting a = 20, b = 16 and h = 24, we get;

Simplifying, we get;



Thus, the area of the trapezoid is 432 square feet.
