Answer: B.
$337.5\text{ ft.}^2$

Explanation:

The area of trapezoid is given by :-

$\text{Area}=(1)/(2)h(a+b)$ , where a and b are the parallel sides and h is the height.

From the given picture, we have

Height (h) = 15 ft

a = 20 ft.

b = 25 ft.

Then , the area of trapezoid is given by :-

$\text{Area}=(1)/(2)(15)(20+25)\\\\\Rightarrow\text{Area}=337.5\text{ ft.}^2$

Hence, the area of trapezoid is
$337.5\text{ ft.}^2$
