25'

O 225 ft?
O 450 ft?
O 320 ft?
O 375 ft?

Answer 1

A. 225 ft²

Explanation:

Area of the front wall of the shed = area of the trapezoid shape

Area of trapezoid = ½(a + b)×h

Where,

a = 20 ft

b = 25 ft

h = 10 ft

Plug the values into the equation

Area of the front wall of the shed = ½(20 + 25)×10

= ½(45)×10 = 45×5

Area of the front wall of the shed = 225 ft²
