Question

Description
Create an object-oriented program that uses inheritance to perform calculations on a rectangle or a square.

Sample Output (Your output should be similar to the text in the following box)

Rectangle Calculator Rectangle or square? (r/s): r Height: 5 Width: 10 Perimeter: 30 Area: 50 Continue? (y/n): y Rectangle or square? (r/s): s Length: 5 Perimeter: 20 Area: 25 Continue? (y/n): n Thank you for using my app

Specifications

• Use a Rectangle class that provides attributes to store the height and width of a rectangle. This class should also provide methods that calculate the perimeter and area of the rectangle.
• Use a Square class that inherits the Rectangle class. This class should set the height and the width of the Rectangle superclass to the length that’s set in the Square subclass.
• The program should determine whether the user wants to enter a rectangle or a square.
• For a rectangle, the program should get the height and width from the user.
• For a square, the program should get the length of the square from the user.

Submission Instructions

1. Write the code to create the program described above.
2. Save your Python source code.
3. Compile, run, and submit the following items (DO NOT submit a zip file) on Canvas:
   • Source code file: Main.py
   • Output screenshot file: Output.jpg or Output.png on IDLE or Thonny.

# Python code for above problem

# parent class
class Shape( object ):
   def __init__(self, height, width):       # constructor that initialises the object with values
       self.height = height
       self.width = width
   def area(self):                           # method that prints the area
       print("Area:",self.height*self.width)
   def perimeter(self):                   # method that prints the perimeter
       print("Perimeter:",2*(self.height+self.width))

# child class
class Rectangle( Shape ):          
   def __init__(self, height, width):
       Shape.__init__(self, height, width)

class Square( Shape ):          
    def __init__(self, length):
       Shape.__init__(self, length, length)

def main():
   while(True):
       shape=input("Rectangle or Square? (r/s): ")
       if(shape[0]=='r'):
            height=int(input("Height: "))
            width=int(input("Width: "))
            rectangle=Rectangle(height, width)
            rectangle.perimeter()
            rectangle.area()
       elif(shape[0]=='s'):
            length=int(input("Length: "))
            square=Square(length)
            square.perimeter()
            square.area()
       else:
            print("Invalid option")
       choice=input("Continue? (y/n): ")
       if(choice[0]!='y'):
            break
   print("Thank you for using my app")
main()

Sample output:

Rectangle or Square? (r/s): r Height: 5 Width: 10 Perimeter: 30 Area: 50 Continue? (y/n): y Rectangle or Square? (r/s): s Length: 5 Perimeter: 20 Area: 25 Continue? (y/n): n Thank you for using my app
