Interface That Inherits Another Interface

IShape inherits from IDrawable: IDrawable declares Draw() and IShape adds Area(). Write a Square class that implements IShape. It takes a side length in its constructor, Draw() returns Drawing a square, and Area() returns side * side. A class that implements IShape must supply BOTH methods. Do NOT write a Main method.

For a square of side 4 the program prints:
Drawing a square
16

Expected Output:

Drawing a square
16
