Given three numbers, create a class Area with  following characteristics. 

•     Must extend Rectangle and Square class.
•     Public function named getSumOfAreas that accept two parameter of double type and return addition of those number.

 

Note: Rectangle and Square class already created. 

Input
    5.5
    5.5
    6.5

   

     Where, 

• The first line is length of Rectangle.
• The second line is width of Rectangle.
• The third line is side of Square.

 

Output
    30.25
    42.25
    72.50

    Where, 

• The first line of output contains area of Rectangle.
• The second line of output contains area of Square.
• The third line of output contains sum of above area.

 

Assume that, 

• Inputs are in double within the range [ 1 to  10^20].

Not sure where to begin, please use code template below:

#include
#include
using namespace std;

//rectangle class
class Rectangle {
  public:
    double areaOfRectangle(double l, double w) {
      if (l > 0 && w > 0)
        return l * w;
      else
        return 0;
    }
};
// Square class
class Square {
  public:
    double areaOfSquare(double s) {
      if (s > 0)
        return s * s;
      else
        return 0;
    }
};
 like cin/cout.

    //write your code here

int main() {

    double l,w,s;
    Area area;
    cin >> l;
    cin >> w;
    cin >> s;
   
    cout << fixed << setprecision(2) << area.areaOfRectangle(l,w) << endl;
    cout << fixed << setprecision(2) << area.areaOfSquare(s) << endl;
    cout << fixed << setprecision(2) << area.getSumOfAreas(area.areaOfRectangle(l,w),area.areaOfSquare(s));
    return 0;
}
