|Not to be nosy, but is this a Homework Assignment?|
Because using a Table may not be the best option for you.
First, how big do you want the table,
Excel 2010 has 1,048,576 rows by 16,384 columns,
but I doubt you want a table that large. :-)
Second, your formula will probably be the same as I posted,
because with a Table you will need to Input both the Length & Width
to do a Lookup into the table to get your Area.
But why do a Lookup, if you already have your L & W?
Now all you need is Price and your done.
It may look pretty, but is it really needed?
See what I mean?
