This is a formula to find the area of a regular polygon with sides of equal length only using the side length.(adsbygoogle = window.adsbygoogle || []).push({});

(ns^{2}cot(180/n))/4

Where n is equal to the number of sides and s is the side length.

Also, knowing radius (r) or apothem (a)

(na^{2}tan(180/n))/4

(nr^{2}sin(180/n)cos(180/n))/4

Has someone found this before?
