Write a C program to calculate the area & perimeter of the rectangle, and the area & circumference of the circle
Problem Statement:
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.
Answer:
/* Calculation of perimeter and area of rectangle and circle */
#include<stdio.h>
#include<conio.h>
main()
{
int l, b, r, area1, perimeter;
float area2, circum;
clrscr();
printf(“\n Enter Length and Breadth of Rectangle”);
scanf(“%d %d”,&l, &b);
area1=l*b; /*Area of rectangle */
perimeter=2*l+2*b; /* Perimeter of rectangle */
printf(“\n Area of Rectangle = %d”, area1);
printf(“\n Perimeter of Rectangle=%d”,perimeter);
Print(“\n\n Enter Radius of circle”);
scanf(“%d”,&r);
area2=3.14*r*r; /* Area of Circle */
circum=2*3.14*4; /* Circumference of a circle */\
printf(“Area of Circle=%f”,area2);
printf(“Circumference of Circle-%f”,circum);
printf(“\n\n\n\n Press any key to exit….”);
getch();
}
