Hello!

To find the area of a trapezoid you use the equation


A = (a + b)/(2) h

A is area
a and b are the base length
h is height

Put in the values you know


A = (20 + 25)/(2) * 15

Add


A = (45)/(2) * 15

Divide


A = 22.5 * 15

Multiply

A = 337.5

The answer is B) 337.5 ft squared

Hope this helps!

Area of the trapezoid = 1/2(b1 + b2) h

b1 = top base
b2 = bottom base
h = height

so
A = 1/2(20 + 25)(15)
A = 1/2(45)(15)
A = 337.5

answer
B. 337.5 ft^2
