Add a second class called RegularPolygon, which will inherit the characteristics of the Figure class. Add the following elements.

Attributes:

$--$ apothem

$--$sidemeasurement

Methods:

$--$get and set the two attributes

$--$ calculate perimeter

$--$ calculate area

Add an example of an octagon and a pentagon to the main file.

Here is the code to complete.
