Question

find the area of this trapezoid. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for the area of a trapezoid

The formula for the area of a trapezoid is \(A=\frac{(a + b)h}{2}\), where \(a\) and \(b\) are the lengths of the parallel sides and \(h\) is the height.

Step2: Identify the values of \(a\), \(b\), and \(h\)

From the trapezoid, \(a = 8\) ft, \(b=20\) ft, and \(h = 9\) ft.

Step3: Substitute the values into the formula
