## Area of a Regular Polygon 3 ft with 11 sides

**Steps:**

Given that Side, a = 3 ft and No of sides, n = 11

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

Put the values in area Formula.

A = 11 * ft² * cot(π/11)/4

Simplify the above equation

A = 84.2907592 ft²

∴ Area of a Regular Polygon 3 ft with 11 sides is 84.2907592 ft²
