Answer:

135 ft^2

Step-by-step explanation:

7yd = 7*3 feet = 21 feet

[tex]area \: of \: trapezoid \\ = \frac{1}{2} (15 + 21) \times 7.5 \\ = \frac{1}{2} \times 36 \times 7.5 \\ = 18 \times 7.5 \\ = 135 {feet}^{2} [/tex]

The answer to this question would be 82.5 because the formula for finding the area of a trapezoid is,
A=a+b /2 h,
Put the numbers in place,
A=15+7/2 7.5,
A=82.5
