You've written a function that does something different from what the instructions asked for. Take another look at the instructions for task 1:

"Create a function named area() that takes a single argument which will be a two-member tuple. area() should return the result of multiplying the first item in the tuple by the second item in the tuple."

Note that the function should take a single tuple argument instead of a list of them, and return a numeric value instead of a list. The provided "dimensions" list won't be used until task 2, and with a comprehension instead of a "map".
