Doing a project for Geometry.
However, I've forgotten how to figure out the surface area of a regular pentagon.
What will the surface area be if all sides equal 1"?
Thanks in advance!

A = 1/2 * apothem * perimeter.

Should be pretty self-explanatory, except I can't remember exactly what the apothem is ... look it up on wikipedia.

EDIT: http://en.wikipedia.org/wiki/Apothem

EDIT2: And oh, yeah, Google is your friend.
