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 house is 600 square feet. Write and solve an equation to find the base of the A-frame house.

Answer 1

60 feet

Explanation:

the area of a triangle is:

area = base*height/2

solve for the base:

base = 2*area/height

and plug in the data:

base = 2*600/20

base = 60

so the base is 60 feet

Answer 2

the area of a triangle is:
area = base*height/2
solve for the base:
base = 2*area/height
and plug in the data:
base = 2*600/20
base = 60
so the base is 60 feet
