Given the following base C++ class,
class area_cl {
public:
double height;
double width;
};
Create two derived classes called rectangle and isosceles that inherit area_cl. Have each class include a function called area()
that returns the area of a rectangle or isosceles triangle, as appropriate. Use parameterized constructors to initialize height and width.
