## Area of a Regular Polygon 3 ft with 9 sides

**Steps:**

Given that Side, a = 3 ft and No of sides, n = 9

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

Put the values in area Formula.

A = 9 * ft² * cot(π/9)/4

Simplify the above equation

A = 55.6364177 ft²

∴ Area of a Regular Polygon 3 ft with 9 sides is 55.6364177 ft²
