Answer to Question #294018 in Python for Rahul

Question

Write a Python class, Rectangle. The class will have instance variables length and width

and a method which will compute the area of a rectangle. Include the constructor and

other required methods to set and get class attributes. Also, include a method isSquare(),

which returns a Boolean value indicating if the shape is a square. (Hint: use @property)

Answer 1
