"""Question3: Create a "Shape" class. Under this class, create two subclasses, "Rectangle" and "Square" classes.
Let the "shape" class have two properties: "width" and "height."
Let the "Rectangle" class inherit from the "Shape" class and add an additional "calculate_area()" method.
Let the "Square" class inherit from the "Shape" class and calculate the area of the square using the same "area_calculate()" method.
Create a "Rectangle" and a "Square" instance,
determine the width and height of each, and calculate the area of each and print the results."""
