Calculate area of equilateral triangle

Here given code implementation process.

//C Program
//Calculate area of equilateral triangle
#include <stdio.h>
#include <math.h>

 ///Calculate area of equilateral triangle by given side
void equilateral_triangle(double side)
{
	//Calculate area of equilateral triangle
	double area = (sqrt(3) / 4) * (side * side);
	//Display the result of right angle triangle area
	printf(" Equilateral triangle  [ side : %lf ] ", side);
	printf("\n Area : %lf\n\n", area);
