find the area of a regular polygon in python

To find the area of a regular polygon in python, we need to know the length of one side of the polygon (s) and the number of sides (n).

We can use the following formula to calculate the area:

main.py
Area = (s^2 * n) / (4 * tan(pi/n))

Here is the python code implementing the above formula:

main.py
import math

def regular_polygon_area(n, s):
    return (s**2 * n) / (4 * math.tan(math.pi / n))

# Example usage
n = 4 # number of sides
s = 5 # length of one side
area = regular_polygon_area(n, s)
print("Area of the regular polygon with", n, "sides and side length", s, "is", area)

11 lines

Output:

main.py
Area of the regular polygon with 4 sides and side length 5 is 25.000000000000004
81 chars
2 lines

Note that we have used the math module to access the value of pi and the tangent function. Also, the output may have a small error due to the precision of floating-point arithmetic.
