Write a Program to find perimeter of Square,Circleand Rectangle

#include <stdio.h>

#define pi 3.14159

main()
 {

    float s,rl,rb,rad,psq,pr,pcir;

    printf("Enter Side of Square \n");

    scanf("%f",&s);

    printf("Enter Length and Breadth of rectangle \n");

    scanf("%f%f",&rl,&rb);

    printf("Enter Radius of Circle \n");

    scanf("%f",&rad);

    psq = 4*s;

    pr = 2*(rl+rb);

    pcir = 2*pi*rad;

    printf("The Perimeter of Square = %f \n",psq);

    printf("The Perimeter of Rectangle = %f \n",pr);

    printf("The Perimeter of Circle = %f\n",pcir);

}

/*

INPUT :

Enter Side of Square

5

Enter Length and Breadth of rectangle

6

7

Enter Radius of Circle

2

OUTPUT :

The Perimeter of Square = 20.000000

The Perimeter of Rectangle = 26.000000

The Perimeter of Circle = 12.566360
