What is the area of the trapezoid ?

Answer:
Step-by-step explanation:
The formula of an area of a trapezoid is:
[tex]A=\dfrac{b_1+b_2}{2}\cdot h[/tex]
b₁, b₂ - bases
h - height
We have:
b₁ = 20 ft, b₂ = 16 ft, h = 24 ft
Substitute:
[tex]A=\dfrac{20+16}{2}\cdot24=\dfrac{36}{2}\cdot24=18\cdot24=432\ ft^2[/tex]
