Find the area of the triangle or quadrilateral.

To find the area of a trapezoid, use this formula:

A = 1/2 · h · (b₁ + b₂)
A = area
h = height
b₁ = base 1
b₂ = base 2

Plug in the numbers given for trapezoid AWEV
1/2 · 3 · (3 + 6)
Then solve
1/2 · 3 · 9 = 13.5

The area of trapezoid AWEV = 13.5 ft²

Follow the same steps for the second trapezoid (Trapezoid EFGH)

A = 1/2 · h · (b₁ + b₂)
A = area
h = height
b₁ = base 1
b₂ = base 2

Plug in the numbers given for trapezoid EFGH
1/2 · 4 · (13 + 8)
Then solve
1/2 · 4 · 21 = 42

The area of trapezoid EFGH = 42 ft²

The answer would be c
