Q: (e) The length and breadth of a rectangle and radius of a circle are input through the keyboard. Write a program to calculate the area and perimeter of the rectangle, and the area and circumference of the circle.

#include <stdio.h>

int main()

{

    double l,b,arearec,perirec,r,areacir,circumcir;

    printf("Enter Length & Breadth of Rectangle\n");

    scanf("%lf%lf",&l,&b);

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

    scanf("%lf",&r);

    arearec=l*b;

    perirec=2*(l+b);

    areacir=3.14*r*r;

    circumcir=2*3.14*r;

    printf("Area of Rectangle is %lf\n",arearec);

    printf("Perimeter of Rectangle is %lf\n",perirec);

    printf("Area of Circle is %lf\n",areacir);

    printf("Circumference of Circle is %lf\n",circumcir);

    return 0;

}
