Add a new property to the Rectangle class named area. It should calculate and return the area of the Rectangle instance

Add a new property to the Rectangle class named area. It should calculate and return the area of the Rectangle instance (width * length).

rectangle.py 
class Rectangle:
    def __init__(self, width, length):
        self.width = width
        self.length = length

    @property
    def area(self):
        return self.width*length
