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.

If the glass costs $3 per square foot for a rectangular piece and $4.75 per square foot for the circular piece, find the total cost of the glass.
