Area of a Polygon
The area of any polygon is given by:
Π
defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.
n is number of sides and s is the length of each side.
The area of a polygon that has infinite sides is the same as the area a circle.
Example: Determine the area of a polygon that has 5 sides and each side is 3 meters in length.
A = (n ∙ s

/ 4) ∙ cot (
Π
/ n) = (45/4) ∙ cot(3.14 / 5) = 15.495 m
