Hi I have written the following code:

class FirstRectangle{ public int rectArea(int l,int b){ int farea = l*b; System.out.println("Required Area::"+farea); return farea; }//method }//class

class SecondRectangle{ public int area(int l, int b){ int sarea = l*b; System.out.println("Required Area::"+sarea); return sarea; }//method }//class

public class MyShape{ public void combinedArea(FirstRectangle r,SecondRectangle sr){ r.rectArea(10,5); sr.area(15,10); }//method public static void main(String []s){ FirstRectangle r = new FirstRectangle(); SecondRectangle sr = new SecondRectangle(); MyShape m = new MyShape(); m.combinedArea(r,sr); }//main }//class

Hi Friend,

```class FirstRectangle{
public int rectArea(int l,int b){
int farea = l*b;
System.out.println("Required Area::"+farea);
return farea;
}
}

class SecondRectangle{
public int area(int l, int b){
int sarea = l*b;
System.out.println("Required Area::"+sarea);
return sarea;
}
}

public class MyShape{
public void combinedArea(FirstRectangle r,SecondRectangle sr){
int area1=r.rectArea(10,5);
int area2=sr.area(15,10);
int sum=area1+area2;
System.out.println("Combined Area is: "+sum);
}
public static void main(String []s){
FirstRectangle r = new FirstRectangle();
SecondRectangle sr = new SecondRectangle();
MyShape m = new MyShape();
m.combinedArea(r,sr);
}
}
```

Thanks

Thanks for the solution. Now its working.

One more thing I need to ask: Is there any provision by which I can directly use farea and sarea for calculating the sum. I mean say the respective calculated values are stored in farea and sarea. Can't I use them directly?
