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.
