haha, i knew all that stuff
not really, i am in algebra II
um... i have a formula of my own!!
The formula for the area of a regular polygon, where A = area, N = the number of sides, and L = the length of each side, is:
A=NL2sin(90(N-2)/N)/4sin(180/N)
off topic slightly, but it works!
i've attached my proof, complete with diagrams
