Write a program to find out area of Square , Rectangle and Circle.

#include <stdio.h>

#define pi 3.14159

main(void)
 {

    float s,rb,rl,rad,asq,ar,acir;

    printf("Enter side of square \n");

    scanf("%f",&s);

    printf("Enter Rectangle breadth and lenght \n");

    scanf("%f%f",&rb,&rl);

    printf("Enter radius of circle \n");

    scanf("%f",&rad);

  

    asq = s*s;

    ar = rb*rl;

    acir = pi*rad*rad;

  

    printf("Area of Square = %f \n",asq);

    printf("Area of Rectangle = %f \n",ar);

    printf("Area of Circle = %f\n",acir);

}

/*

INPUT :

Enter side of square

12

Enter Rectangle breadth and length

1

3

Enter radius of circle

5

OUTPUT :

Area of Square = 144.000000

Area of Rectangle = 3.000000

Area of Circle = 78.539749
