Question

Python Program:

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

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.

Sample Output (Your output should be similar or can be the same 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.

Answer 1

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 __init__(self,length):
super().__init__(length,length)

if __name__== "__main__":
print("Rectangle Calculator")
while True:
c=input("Rectangle or Square? (r/s): ")
if c=='r':
l=int(input("Heigth: "))
b=int(input("Width: "))
rect=Rectangle(l,b)
print("Perimeter: ",rect.perimeter())
print("Area: ",rect.area())
if c=='s':
l=int(input("Length: "))
squa=Square(l)
print("Perimeter: ",squa.perimeter())
print("Area is: ",squa.area())
s=input("Continue? (y/n): ")
if s=='n':
break
print("Thank you for using my app")

Output:
