Question

Find the area of the trapezoid below.

Answer 1

A = 18 cm²

Explanation:

the area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

here h = 3 , b₁ = 8 , b₂ = 4 , then

A =
`(1)/(2)` × 3 × (8 + 4) = 1.5 × 12 = 18 cm²
