    My C++ solution 

    #include <iostream>

using namespace std;
/*
 * Create classes Rectangle and RectangleArea
 */
class Rectangle{
  protected:
  int width;
  int height;
  
  public:
  Rectangle(){
    width = 0;
    height = 0;
  }
  Rectangle(int _w,int _h) {
     width = _w;
     height = _h;
  }
  void display(){
    std::cout<<width<<" "<<height<<std::endl;
  }
  
  
};

class RectangleArea: public Rectangle{
        public:
        void read_input(){
            std::cin >> width;
            std::cin >> height;

        }

        void display(){
            std::cout << width*height<<std::endl;
        }        
};

int main()
{
    /*
     * Declare a RectangleArea object
     */
    RectangleArea r_area;
    
    /*
     * Read the width and height
     */
    r_area.read_input();
    
    /*
     * Print the width and height
     */
    r_area.Rectangle::display();
    
    /*
     * Print the area
     */
    r_area.display();
    
    return 0;
}
