Write a program in c to calculate the area and perimeter of a rectangle.

#include<stdio.h>
int main()
{
int l,b;
float area,peri;
printf("Enter the length of rectangle\n");
printf("Enter the length of rectangle\n");
scanf("%d",&l);
scanf("%d",&b);
area=l*b;
peri=2*(l+b);
printf("Area=%f\n",area);
printf("Perimeter=%f",peri);
return 0;
}
