Question

4. Asia is designing a triangular-shaped window with a height of 15 inches and

an area of 135 square inches. What is the length of the base of the window?

Answer 1

18in

Explanation:

Given data

Height h= 15 in

Area= 135 in^2

The expression for the area is given as

Area= 1/2 Base * Height

substitute

135= 1/2* Base*15

135= 7.5 Base

Base= 135/7.5

Base= 18 in

Hence the base is 18in
