I don’t know how to do this i need help please

Answer 1

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`
