The length and breadth of a rectangle and radius of a circle are input through the keyboard. write a program to calculate the area and perimeter of the rectangle, and the area and circumference of the circle

 #include<stdio.h>

# include<conio.h>

int main(){

float l,b,r, ca,cc,ra ,rp;

printf("Enter the length of rectangle:");

scanf("%f",&l);

printf("Enter the breadth of rectangle:");

scanf("%f",&b);

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

scanf("%f",&r);

ra=l*b;

rp=2*(l+b);

ca=3.14*r*r;

cc=2*3.14*r;

printf("\nThe area of rectangle :%0.2f", ra);

printf("\nThe perimeter of rectangle :%.2f ,rp);

printf("\nThe  area of circle:%2f:",ca);

printf("\n The circumference of circle:%.2f",cc);

return 0;

}

 output---Enter the length of rectangle:3

                     Enter the breadth of rectangle:5

                      Enter the radius of circle:6

                    The area of rectangle :15.00

                     The perimeter of rectangle :16.000

                     The  area of circle:113.04000

                     The circumference of circle:37.68


output--
