Question

An A-frame cabin has a triangular front with a base of 30 ft. and a height of 20 ft. If the front isto be glass that costs $3 per square foot, what will the glass cost

Answer 1

First, find the area of the triangluar shape. The formula for the area of a triangle, is:

`A=(1)/(2)b* h`

Use b=30ft and h=20ft:

`\begin{gathered} A=(1)/(2)(30ft)*(20ft) \\ =300ft^2 \end{gathered}`

Since the cost per square foot is $3, multiply 300 times 3 to find the total cost of the glass:

`300*3=900`

Therefore, the cost will be $900.
