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 " +

                          obj.Circumference(a));

        return (4 * a) 
  
# Driver code 
a = 5
c = Circumference(a)

<?php 
// PHP program to find

echo "Circumference of a ". 
              "square is ",  
         Circumference($a);

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

C++

// C++ Program to find  
// Circumference of a rectangle 
#include <iostream>
