What are the steps of finding the area of a regular polygon when you know the side length
1) find the central angle
2) Look at the smaller triangle that is make with the central angle and vertices and the side length
3) Cut that triangle in half to make a right triangle
4) Use trig functions to find the length of the apothem
5) plug our known information now into the formula (.5*n*a*s)
