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

You're almost there. Just have to multiply self.width by self.length, not length.

tried multiplying like that but not still giving an error

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

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

class Rectangle: def init(self, width, length): self.width = width self.length = length @property def area(self): return self.width * self.length

try it worked for me!

class Rectangle: def init(self, width, length): self.width = width self.length = length

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