Program:

class Rectangle:
def Area(self,l,b):
self.l=l
self.b=b
return l*b
class Square:
def Area(self,side):
self.side=side
return side*side

Rect_obj=Rectangle()
print("Area of Rectangle:",Rect_obj.Area(6,4),"Sqr.unit")

Sqr_obj=Square()
print("\nArea of Square:",Sqr_obj.Area(6),"Sqr.unit")

Expected O/P:

Area of Rectangle: 24 Sqr.unit

Area of Square: 36 Sqr.unit
