Can't find why it is not working.

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

I get Bummer: No area attribute error when I try to check my work. I do not understand what attribute do I need to give.

rectangle.py 
class Rectangle:
    def __init__(self, width, length):
        self.width = width
        self.length = length
    @property
    def area(self):
        return self.width * self.lenght

You have a typo:

self.lenght

should be

self.length
