I need assistance on this.

Summary

In this lab, you create a programmer-defined class and then use it in a Python program. The program should create two Rectangle objects and find their area and perimeter.

Instructions

1. Open the class file named Rectangle.py
2. In the Rectangle class, create two attributes namedlengthandwidth.
3. Write a publiccalculateAreamethod and a publiccalculatePerimetermethod to calculate and return the area of the rectangle and the perimeter of the rectangle.
4. Open the file named MyRectangleClassProgram.py.
5. Set the length ofrectangle1to 10.0 and the width to 5.0. Set the length ofrectangle2to 7.0 and the width to 3.0.
6. Print the value ofrectangle1's perimeter and area, and then print the value ofrectangle2's perimeter and area.
7. Execute the program and verify that the output is correct.
