First, find the area of the triangle.

Start with the area of a triangle formula

Plug in b=30 and h=20

Multiply

Divide

So the area of the triangle is 300 square feet.

Now multiply the area of the rectangle by the cost per square foot to get:

So it will cost a total of $900 to cover the triangular front with glass.

In this problem, first, you need to find the area of the triangular front face of the cabin, then you need to multiply the cost per square foot of the glass by the number of square feet in the area.
The area of a triangle is found by:
where b = length of the base and h = the height of the triangle.
In this problem, b = 30ft. and h = 20ft. so you make the appropriate substitutions into the formula above.

sq.ft.
To find the cost (C) of 300 sq.ft. of glass at $3.00 per square foot, you will multiply the area (300 sq.ft.) by the cost ($3.00 per sq.ft.),

So the cost of the glass for the front face of the cabin is $900.00
