Hi there, Ashmit! You are doing great, but you forgot something in the perimeter function that you didn't forget in the area function. Remember that length and width are properties on the object. Just as you specified self.l and self.w in the area function, you will need to reference them that way in the perimeter method.

Hope this helps! :sparkles:
