Question

Find the area. This is a trapezoid, with bases that measure 5 feet and 10 feet, and a height of 4 feet.

Answer 1

A = 30 ft²

Explanation:

the area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (b₁ + b₂)

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

A =
`(1)/(2)` × 4 × (5 + 10) = 2 × 15 = 30 ft²
