[H]. (e) 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.

void main()
{
 float l, b, r, ar, pr, ac, cc ;
 printf("Enter Length Of Rectangle : ");
 scanf("%f",&l);
 printf("Enter Breadth Of Rectangle : ");
 scanf("%f",&b);
 printf("Enter Radius Of Circle : ");
 scanf("%f",&r);
 ar=l*b;
 pr=2*(l+b);
 ac=22*r*r/7;
 cc=2*22*r/7;
 printf("Area Of Rectangle = %f",ar);
 printf("\nPerimeter Of Rectangle = %f",pr);
 printf("\nArea Of Circle = %f",ac);
 printf("\nCircumference Of Circle = %f",cc);
 getch();
