Kitchen Measurements

Ok, new experience, I quickly tried to put together some type of file to show the measurements that I took of the kitchen.  It is not good - but hopefully it will help and make some sense. I did determine that if I did it right, we need like 38 SQ FT of tile or some material.   At least that will help w/ the budgeting process.  But it seems like so much, I am not sure I did it right.
