Answer:
D. 30 Ft.
Step-by-step explanation:
Split the trapezoid into two shapes for an easier process .
The ideal split shall result in two shapes: A rectangle and a right triangle .
Rectangle Formula: L · W = A
Substitution: 6 · 4 = 24 Ft.
Right Triangle Formula: ( B · H ) ÷ 2 = A
Substitution: ( 3 · 4 ) ÷ 2 = 6 Ft.
Add the separate areas together to get the final result .
24 + 6 = 30 Ft.
