1. Find the area of the given triangle as step 1.

A = 1/2(base)(height)....This is the general formula used to find the area of a triangle when base and height are given.

A = 1/2(30)(20)

A = 1/2(600)

A = 300 square feet

The front will cost \$3 per square feet and we found 300 square feet. So, multiply \$3 by 300 square feet and you will have the cost of the glass.
