Please help!! The exterior walls of a regular pentagon shaped courthouse must be painted. Each wall of the courthouse is 80ft by 18ft. How much paint is necessary?

I think 7200ft of paint is needed. I may be wrong.
OpenStudy (anonymous):
Okay. How did you come up with that?
OpenStudy (handsomechickenlover):
Well I multiplied 80 times 18 then I multiplied the answer by 5. Because a pentagon has 5 sides.
OpenStudy (anonymous):
That would make sense. I couldn't figure out if I was looking for the perimeter or not
OpenStudy (handsomechickenlover):
You needed to find the area of one wall and multiply by 5. I was glad to help.
