Question

The front of an A-frame house is in the shape of a triangle. The height of the house is 20 feet. The area of the front of the A-frame is 600 ft.² Write and solve an equation to find the base of the A-frame house

Answer 1

h = height of front of house = 20
b = base of fornt of house
A = area of front of house = 600

Recall the following equations :

A = 1/2 bh
600 = 1/2 b (20)
600 = 10 b
60 = b
