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 the output shown in Expected Output.

Expected Output:

Drawing a square↵
16↵

= newline. The output ends with a newline — print one after the last line.
