23126.1066672 cm²
231261.0666718 mm²

Steps:

Given that Side, a = 21 ft and No of sides, n = 5

We know that, Area = n * a² * cot(π/n) /4

Put the values in area Formula.

A = 5 * ft² * cot(π/5)/4

Simplify the above equation

A = 758.7305337 ft²

∴ Area of a Regular Polygon 21 ft with 5 sides is 758.7305337 ft²
