Answer:
336 ft²
Step-by-step explanation:
The figure is composed of a rectangle and a right triangle
A of rectangle = length × breadth = 24 × 12 = 288 ft²
A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 32 - 24 = 8 ft and h = 12 , then
A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²
composite area = 288 + 48 = 336 ft²
