Perimeter. I tested this in PyCharm it does what it should do but I probably didn't understand correctly the task. Help

I messed something up please help me correct it.

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)

Very close! You just forgot to add the "@property" decorator for "perimeter".
