Task 2 instructs you to "Create an array called areas", but the code above has a new property called areas instead.

Remove that property and create the new array at the bottom of the provided code where you can use the use the 3 rectangle objects to construct it. Be sure to use the object names and methods and don't calculate the values yourself.
