Question

What is the area, in square inches, of the trapezoid below

Answer 1

A = 89.2 in²

Explanation:

The area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 8, b₁ = 6.6, b₂ = 15.7 , then

A =
`(1)/(2)` × 8 × (6.6 + 15.7) = 4 × 22.3 = 89.2 in²

Answer 2

89.2 in^2

Explanation:

1/2(15.7+6.6)(8)

=89.2 in^2
