# Write a program in 'C' Language to calculate the area and perimeter of thhe rectangle?

**Q. ****The Length and breadth of a rectangle and radius of a circle are input through thhe keyword. Write a program to calculate the area and perimeter of thhe rectangle, and the area and circumference of the circle?**

**Solve: **

#include<stdio.h>

#include<conio.h>

int main()

{

int l,b,r;

int ans;

printf("\n Enter the value of rectangle length: ");

scanf("%d", &l);

printf("\n Enter the value of rectangle Breadth: ");

scanf("%d", &b);

ans=l*b;

printf("\n Area of the rectangle is:=%d",ans);

ans=2*l+2*b;

printf("\n Perimeter of the rectangle:=%d",ans);

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

scanf("%d", &r);

ans=3.14*r*r;

printf("\n Area of the circle:=%d",ans);

ans=2*3.14*r;

printf("\n circumference of the circle:=%d",ans);

}
