Question

What is the area of the trapezoid
O 120in
O 140in
O 91in
O 182in

Answer 1

A = 91 in²

Explanation:

The formula of an area of a trapezoid:

`A=(b_1+b_2)/(2)\cdor h`

b₁, b₂ - bases

h - height

We have b₁ = 20in, b₂ = 6in and h = 7in.

Substitute:

`A=(20+6)/(2)\cdot7=(26)/(2)\cdot7=(13)(7)=91\ in^2`
