In this challenge, we practice using arithmetic operators. Check out the attached tutorial for resources.

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.

getArea

1. Data Type Parameter Description Number length A number denoting the length of a rectangle. Number height A number denoting the height of a rectangle.

getPerimeter(length, height)

2. Data Type Parameter Description Number length A number denoting the length of a rectangle. Number height A number denoting the height of a rectangle.

• 1 <= length,width <= 100
• length and height are scaled to at most three decimal places.

Function Return Type Description getArea Number The area of a rectangle having sides length and width. getPerimeter Number The perimeter of a rectangle having sides length and width.

3 4.5

13.5 15

The area of the rectangle is length X width = 3 X 4.5 = 13.5.

The perimeter of the rectangle is 2 X (length + height) = 2 X (3 + 4.5) = 15.
