# Python Math: Calculate the area of a regular polygon

## Python Math: Exercise-28 with Solution

Write a Python program to calculate the area of a regular polygon.

**Sample Solution**:-

**Python Code:**

```
from math import tan, pi
n_sides = int(input("Input number of sides: "))
s_length = float(input("Input the length of a side: "))
p_area = n_sides * (s_length ** 2) / (4 * tan(pi / n_sides))
print("The area of the polygon is: ",p_area)
```

Sample Output:

Input number of sides: 4 Input the length of a side: 20 The area of the polygon is: 400.00000000000006
