Answer 1

Answer:

//program for area and perimeter

public class Rectangle

{

     public static void main(int l, int b)

     { System.out.println("length="+l);

       System.out.println("breadth="+b);

       int a=l*b;

       System.out.println("area="+a);

       int p=2*(l+b);

       System.out.println("perimeter="+p);

}

This is the normal method, but you can also use switch case for making it easier. (if you know)

Hope you understood!!!
