GeeksforGeeks - Summer Carnival Banner

The circumference of a figure is the sum of all the side lengths. To calculate the circumference of square, length of one of the side is required as all sides are equal. To calculate the circumference of rectangle, length and breadth of rectangle is required. 
Circumference of a Square: 
 

The circumference of a square is given by the formula: 
 

C = 4 * a
where a is the side length.

Examples : 
 

input: 4
output: 16

input: 3
output: 12

 



C++




// CPP program to find
// Circumference of a square
#include <bits/stdc++.h>
using namespace std;
 
int Circumference(int a)
{
    return 4 * a;
}
 
// Driver Code
int main()
{
    int a = 5;
    cout << "Circumference of"
         <<" a square is "
         << Circumference(a);
    return 0;
}

import java.io.*;
class GFG
{
    int Circumference(int a)
    {
        return 4 * a;
    }
 
    // Driver code
    public static void main(String args[])
    {
        GFG obj = new GFG();
        int a = 5;
        System.out.println("Circumference of " +
                                "a square is " +
                          obj.Circumference(a));
    }

Python3




# Python3 Program to find
# Circumference of a square
 
def Circumference(a):
        return (4 * a)
 
# Driver code
a = 5
c = Circumference(a)
print("Circumference of a " +
       "square is % d" % (c))

C#




// C# program to find Circumference
// of a square
using System;
 
class GFG
{
 
    static int Circumference(int a)
    {
        return 4 * a;
    }
 
    // Driver Code
    public static void Main()
    {
        int a = 5;
 
        Console.WriteLine("Circumference" +
                       " of a square is " +
                         Circumference(a));
    }

PHP




<?php
// PHP program to find
// Circumference of a square
 
function Circumference($a)
{
    return 4 * $a;
}
 
// Driver Code
$a = 5;
echo "Circumference of a ".
              "square is ",
         Circumference($a);

Javascript




<script>
 
// Javascript program to find
// Circumference of a square
function Circumference(a)
{
    return 4 * a;
}
 
// Driver Code
    let a = 5;
    document.write("Circumference of"
        +" a square is "
        +Circumference(a));
 
// This code is contributed by Manoj
 
</script>

Output : 
 

Circumference Of a square is 20

Circumference of a rectangle: 
 

The circumference of a rectangle is given by the formula: 
 

C = 2 * (l + W)
where l is the length and W is the width.

Examples : 
 

input: 2 4
output: 12

input: 4 6
output: 20
