I can't see my error

The challenge is: Let's add one more property to our Rectangle class. This time, add a perimeter property that returns the perimeter of the rectangle (length * 2 + width * 2).

Please help me, I don't know what I'm doing wrong, Jack

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

    @property
    def area(self):
        return self.width*self.length
    def perimeter(self):
        return self.length * 2 + self.width * 2

Jack;

perimeter should be a @property too, right? ;-)

Treehouse has helped me so much. I didn't even know how to code, and after just doing treehouse for a bit, I fell like I can make basic projects with quite a few languages!
