Anyone Can Solve This Problem? (In the below function some mistake. please solve and put correct answer.)

Question

class Rectangle:
def __init__(s, a, b, c):
s.a = a
s.b = b
s.c = c

def x_y(s):
return s.a * s.b * s.c

@classmethod
def n_m(cls, side_length,sde_length):
return cls(side_length, side_length,sde_length)

m = Rectangle.n_m(100)
print(m.x_y())

Answer 1

the function n_m needs two parameters but you call it with only one parameter (100)
