The length and width 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 a circle.

#include<stdio.h>
void main()
{
	float length,width,radius,area_of_R,peri_m,area_of_C,circum_;
	printf("Enter length of rectangl = ");
	scanf(" \n %f",&length);
	printf("Enter width of rectangl = ");
	scanf(" \n %f",&width);
	area_of_R=length*width;
	printf("\n Area of rectangle = %f",area_of_R);
	peri_m=2*(length+width);
	printf("\n Perimeter of rectangle = %f",peri_m);
	printf("\n Enter length of radius = ");
	scanf("%f",&radius);
	area_of_C=22*radius*radius/7;
	printf("\n Area of circle = %f",area_of_C);
	circum_=22*2*radius/7;
	printf("\n Circumference of circle = %f",circum_);
