# --description--

In this project you will use object oriented programming to create a Rectangle class and a Square class. The Square class should be a subclass of Rectangle and inherit methods and attributes.

You can access [the full project description and starter code on Repl.it](https://repl.it/github/freeCodeCamp/boilerplate-polygon-area-calculator).

After going to that link, fork the project. Once you complete the project based on the instructions in 'README.md', submit your project link below.

We are still developing the interactive instructional part of the Python curriculum. For now, here are some videos on the freeCodeCamp.org YouTube channel that will teach you everything you need to know to complete this project:

# --hints--

It should create a Rectangle class and Square class and pass all tests.

```js

```

# --solutions--

```js
/**
  Backend challenges don't need solutions,
  because they would need to be tested against a full working project.
