Given the apothem and length of a side

f you know the apothem (the perpendicular distance from center to a side. See figure above) and the length of a side, first determine the perimeter by mutiplying the side length by N. The area is given by

area =ap/2 ; where

A is the length of the apothem

Pis the perimeter

area=9.7*8*8/2

area=9.7*8*4

area=310.4 m square
