Hello everyone, I would like your help with a question called shapeArea.

I have had some difficulty applying logic to this exercise.

A `1`

-interesting polygon is just a square with a side of length `1`

. An `n`

-interesting polygon is obtained by taking the `n - 1`

-interesting polygon and appending `1`

-interesting polygons to its rim, side by side.

What is the best tip you can give me regarding the content of this question?
