[H] Write C programs for the following:

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

#include <stdio.h>

#include <stdlib.h>

 

int main()

{

    float lenght,width,radius,areaR,perimeterR,areaC,circumferenceC;

    printf("\t\tEnter The Lenght = ");

    scanf("%f",&lenght);

    printf("\n\t\tEnter the width = ");

    scanf("%f",&width);

    areaR=lenght*width;

    perimeterR=2*(lenght*width);

    printf("\n\t\tArea of the rectangle = %f",areaR);

    printf("\n\t\tPerimeter of Rectangle = %f",perimeterR);

    printf("\n\n\t\tEnter the value of radius =");

    scanf("%f",&radius);

    areaC=3.14*radius*radius;

    circumferenceC=2*3.14*radius;

    printf("\n\t\tArea of the Circle = %f",areaC);

    printf("\n\t\tCircumference of Circle = %f\n",circumferenceC);

    return 0;
