class Rectangle:
    def __init__(self,length,width):
        self.length=length
        self.width=width
    def area(self):
        return self.length*self.width
    def perimeter(self):
        return 2*self.length+2*self.width
class Square(Rectangle):
    def set_side (self):
        if self.length!=self.width:
            
    
a=Rectangle(3,5)
print (a.area())
print (a.perimeter())
b=Rectangle(5,7)
print (b.area())
print (b.perimeter())
c=Rectangle(4,4)
print (c.area())
print (c.perimeter())

I bombed on the rest.
