Find the Area of Pentagon

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);
