the area is

Explanation:

Step1: Apply trapezoid area formula

The formula for the area of a trapezoid is \(A=\frac{(b_1 + b_2)h}{2}\), where \(b_1\) and \(b_2\) are the lengths of the parallel sides and \(h\) is the height. Here, \(b_1 = 21\) yd, \(b_2=9\) yd, and \(h = 7\) yd.

Step2: Substitute values into formula
