Create a base class named rectangle that contains lenght and width data members.
kumpel [21]

Answer:

class Rectangle:  

   

   def __init__(self, length, width):

       self.length = length

       self.width = width

       

   

   def area(self):

       area = self.length*self.width

       return area

   

   

class Box (Rectangle):

   

   def __init__(self, length, width, height):

       super().__init__(length, width)

       self.height = height

       

   def volume(self):

       volume = self.length * self.width * self.height

       return volume

   

   def area(self):

       area = 2*(self.length*self.width) + 2*(self.length*self.height) + 2*(self.width*self.height)

       return area

rec_1 = Rectangle(2,4)

box_1 = Box(2,2,6)

print(box_1.length)

print(box_1.area())

   

print(rec_1.length)

print(rec_1.area())

Explanation:

The programming language used is python.

class Rectangle

The class Rectangle is created with attributes length and width.

The class attributes are initialized using the __init__ constructor.

In the rectangle class, a method/function is declared to return the area of the rectangle.

class Box

This class is a child of rectangle and it inherits all its attributes and methods,

It has an additional attribute of depth and its constructor is used to initialize it.

The class contains a volume function, that returns the volume and an override function 'area()' that displaces the area from the parent class.

Finally, some instances of both classes are created.
