(Geometry: area of a hexagon) Write a program that prompts the user to enter the 
side of a hexagon and displays its area. The formula for computing the area of a 
hexagon is 
Area =(3√3 / 2)s².
#Beginner
In gcc c++ compiler using namespace std;

#include<iostream>
#include<cmath>
using namespace std;

int main()
{
float side;
cout<<"Enter the side :";
cin>>side;
float area=3*sqrt(3)*pow(side,2)/2;
cout<<"the area of the hexagon :"<<area;
return 0;
}
copy

Output
Enter the side :4
the area of the hexagon :41.5692
