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 square feet. Write and solve an equation to find the base of the A-frame house.
Area of triangle = (1/2) base * height
600 = (1/2) base * 20
600 =10 * base
600 / 10 = base = 60 ft
