Day 1: Arithmetic Operators (10 Days of Javascript)

Task:

Complete the following functions in the editor below:

1. getArea(length, width): Calculate and return the area of a rectangle having sides length and width.
2. getPerimeter(length, width): Calculate and return the perimeter of a rectangle having sides length and width.

The values returned by these functions are printed to stdout by locked stub code in the editor.
