We are asked to find the area of the trapezoid.
Recall that the area of the trapezoid is given by

Where b₁ is the length of base 1 that is 8.8 ft
b₂ is the length of base 2 that is 5.3 ft
h is the height that is 4 ft
Let us substitute the given values into the above formula

Therefore, the area of the trapezoid is 28.2 ft²
