Construction. An Aframe cabin has a triangular front with a base of 30 ft and a
height of 20 ft. If the front is to be glass that costs $3 per square foot, what will the
glass cost?

algebra 
PsyDAG,
Area = 1/2 base * height = square footage
Multiply that product by $3.
I hope this helps. Thanks for asking.
