Program to find the perimeter of the rectangle

Explanation

A rectangle has four sides in which sides opposite to each other are equal. The perimeter of the rectangle is the area around its outside.

Suppose a, b, c, d are the four sides of rectangle.

a=c and b=d

Perimeter Of Rectangle= a+ b+ c+ d= a+ b+ a+ b= 2(a + b).

Algorithm

Define Values for the side of the rectangle
Apply values in the formula.
Print the Perimeter.

Complexity

O(1)

Solution

Python

a=c=2 # in rectangle sides opposite to each other are equal in length
b=d=4 # length of opposite sides
Perimeter = 2*(a+ b)
print("Perimeter of rectangle is: ");
print(Perimeter); 

Output:

Perimeter of Rectangle is:  12

C

#include<stdio.h>
                   int main() 
                   { float a , b, c, d ,perimeter;
		        a= c= 5;
                                     b=d= 4;
		           perimeter = 2*(a+b);
                                  printf("\n\n Perimeter of Rectangle is : %f",perimeter);
                       return (0);
    }

Output:

Perimeter of Rectangle is: 18.00000

JAVA

public class Main
 {
   public static void main (String args[])
	{      float a ,b, c, d, perimeter;
                    a=c= 5;
                    b=d=4;
                    perimeter  = 2*(a+b);
            System.out.println("Perimeter of Rectangle is: "+perimeter);
	}}

Output:

Perimeter of Rectangle is: 18.0

C#

using System;
class main
{   static void Main() 
    {
      float  a , b, c, d, perimeter;
      a=c=3;
      b=d=6;
 
     perimeter =2*(a+b);
    Console.WriteLine("Perimeter of Rectangle is: "+perimeter);
    }}

Output:

Perimeter of Rectangle is: 18

PHP

<?php
       $a = $c=5 ;
       $b = $d=6 ;
       $Perimeter = 2*($a + $b);
       echo("Perimeter of Rectangle is: ");
       echo($Perimeter);
?>

Output:

Perimeter of Rectangle is: 22
