Question

The triangle's height is 1.5 times the base's length. If the height is 18 ft, what is the area?

Answer 1

108 square feet

Explanation:

It is helpful to know the base length, which we can find from ...

1.5 · base = 18 ft

base = 18 ft/1.5 = 12 ft

Then the area is ...

A = (1/2)bh = (1/2)(12 ft)(18 ft) = 108 ft²

The area is 108 ft².
