Question

Find the areas of the trapezoids

Answer 1

12 units²

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 = 4 ( perpendicular distance between the bases ) and

b₁ = SR = 2, b₂ = TA = 4 , then

A =
`(1)/(2)` × 4 × (2 + 4) = 2 × 6 = 12 units²
