Design a class Parallelogram that contains two private data members: -  double length, -  double height. Parallelogram class should also have following public methods: -  parameterized constructor, -  a method to calculate area of parallelogram. Design another class Rectangle that inherits from Parallelogram (since a Rectangle is-a Parallelogram). Class Rectangle should have the following public members: -  parameterized constructor, -  a method to calculate perimeter, -  a method to tell if the Rectangle object is a Square. Develop the main function to fully test these two classes. Note: 1. please use multiple files (separate compilation)  2. length and height should be protected members in the base class, as you need them to calculate perimeter of a rectangle.

Design a class Parallelogram that contains two private data members:

  • -  double length,

  • -  double height.

    Parallelogram class should also have following public methods:

  • -  parameterized constructor,

  • -  a method to calculate area of parallelogram.

    Design another class Rectangle that inherits from Parallelogram (since a Rectangle is-a Parallelogram). Class Rectangle should have the following public members:

  • -  parameterized constructor,

  • -  a method to calculate perimeter,

  • -  a method to tell if the Rectangle object is a Square.

    Develop the main function to fully test these two classes.

Note:

1. please use multiple files (separate compilation) 
2. length and height should be protected members in the base class, as you need them to calculate perimeter of a rectangle.
