class Shape

{

      int i=10,j=20;

      void area(){
      System.out.println("Find area of rectangle and square:");
       }

}

class Rectangle extends Shape

{

      int l=10,b=5;

      void areaOfRectangle(){
             area();
         System.out.println("Area of Rectangle: "+l*b);
      }

}

class Square extends Rectangle{ int side=5;

      void areaOfSquare(){
             areaOfRectangle();
         System.out.println("Area of Square: "+(side*side));
      }

}

class MultiLevelInheritanceExample{

      public static void main(String args[]){
      Square a=new Square();
          a.areaOfSquare();
      }
