Question

The expression (h) (b, + b₂) gives the area of a trapezoid, with b, and b, representing the two base lengths of a trapezoid and h representing the height. Find the area of a trapezoid with base lengths 4 in. and 6 in. and a height of 8 in. (Lesson 10.2)​

Answer 1

A = 40 in²

Explanation:

the area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (b₁ + b₂)

where h is the height between the bases b₁ and b₂

here h = 8 , b₁ = 4 , b₂ = 6 , then

A =
`(1)/(2)` × 8 × (4 + 6)

= 4 × 10

= 40 in²
