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

Step-by-step explanation:

The area of trapezoid is given by :-

$\text{Area}=\dfrac{1}{2}h(a+b)$ , 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 :-

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

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