class Rectangle:
def __init__(self,length=0,width=0):
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,side):
self.side=side
return side*side
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())
A little closer.
