Calculate Area of Rectangle and Triangle using Single Inheritance

class Rectangle


           {


               int l,b;


               Rectangle(int x,int y)


                 {


                    l=x;


                    b=y;


                 }


                    int getRectangle()


                     {


                        return l*b;


                     }


           }


                   class Triangle extends Rectangle


                      {


                          float a;


                          Triangle(int v,int u)


                             {


                                 super(u,v);


                             }


                                 float getTriangle()


                                    {


                                        a=(float)l/2*l*b;


                                        return (a);


                                    }


                     }


                             class RectangleTriangle


                                 {

                                          {


                                              Triangle m=new Triangle(500,80);


                                              System.out.println("Area of Rectangle is : " +m.getRectangle());


                                              System.out.println("Area of Triangle is : "+m.getTriangle());


                                          }


                                 }
