Python: Program for Area of Rectangle, Circle, and Square

 Below is the program which calculates the areas of Rectangle, Circle, and Square. It takes the inputs from user such as length and width for Rectangle, radius for Circle, and side of Square for Square.

Code:

length = int(input("Enter the length of the Rectangle "))

width = int(input("Enter the width of the Rectangle "))

radius = int(input("Enter radius of Circle "))

side = int(input("Enter side of the Square "))

class Area:

    def __init__(self, length, width, radius, side,):

        self.length = length

        self.width = width

        self.radius = radius

        self.side = side

 

    def Rect_area(self):

        rect_area = self.length*self.width

        print(f"Area of the Rectangle = {rect_area} Sq.Units")

    def Cir_area(self):

        cir_area = 3.14*self.radius**2

        print(f"Area of circle = {cir_area} Sq.Units")

   

    def Squ_area(self):

        squ_area = self.side**2

        print(f"Area of Square = {squ_area} Sq.Units") 

 

rectangle = Area(length, width, radius, side)

circle = Area(length, width, radius, side)

square = Area(length, width, radius, side)

rectangle.Rect_area()

circle.Cir_area()

square.Squ_area()

Output:

Enter the length of the Rectangle 5

Enter the width of the Rectangle 6

Enter radius of Circle 4

Enter side of the Square 7

Area of the Rectangle = 30 Sq.Units

Area of circle = 50.24 Sq.Units

Area of Square = 49 Sq.Units
