I'm going to explain what is going on in the code first. You are assigning three constants. The height, width, and the area. To get to the area of something you must multiply the height and the width. In this example, I assume you know what is going on and your issue is the bug you are getting. This is because there is not varible named "Area" or "Width". To fix your code change "Area" to "height" and change "Width" to "width". Lowercase is important to helping the computer understand your code. Hope this helped!
