Question

Find the area of the compound shape​

Answer 1

15 units²

Explanation:

The figure is a trapezoid, whose area (A) is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

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

Here h = 3 , b₁ = 3, b₂ = 7 , then

A =
`(1)/(2)` × 3 × (3 + 7) = 1.5 × 10 = 15 units²
