Find the Area of Pentagon

The area of a regular pentagon (a polygon with five sides of equal length) can be calculated using the following formula:

A = (1/4) * sqrt(5 * (5 + 2sqrt(5))) * s^2

Where A is the area of the pentagon and s is the length of one of its sides.

Here given code implementation process.

//C Program
//Find the Area of Pentagon
#include <stdio.h>

#include <math.h>
 //Calculate area of pentagon by given side
void pentagon_area(double side)
{
	//Calculate Formula
	//¼√5(5+2√5)side²
	double area = ((double) 1 / 4) * (sqrt(5 * (5 + 2 * (sqrt(5)))) * (side * side));
	//Display the result of pentagon area
	printf(" Pentagon  [ Side : %lf ] ", side);
	printf("\n Area : %lf\n\n", area);
}
int main()
{
	//Test Cases  
	pentagon_area(6);
	pentagon_area(4);
	pentagon_area(3.5);
	return 0;
}

Output

 Pentagon  [ Side : 6.000000 ]
 Area : 61.937186

 Pentagon  [ Side : 4.000000 ]
 Area : 27.527638

 Pentagon  [ Side : 3.500000 ]
 Area : 21.075848
