Given:

ABCD is a trapezoid.


\bar{BC}\bar
BC=20in\text{ and }AD=28in.
The\text{ distance between }\bar{BC}\text{ and }\bar{AD}\text{ is 7 in.}

Required:

We need to find the area of the trapezoid ABCD.

Step-by-step explanation:

The side length of the first base, a =20 in.

The side length of the second base, b =28 in.

The height of the trapezoid, h =7 in.

Consider the area of the trapezoid formula.


A=(a+b)/(2)h

Substitute a =20 , b =28, and h =7 in the formula.


A=(20+28)/(2)*7
A=168in^3

Final answer:


A=168in^3
