Thanks to Jordan, Scott, and Erik!

It was great to get your solution! I also like it a lot that you explained your work.

Now, I don't mean to complain (too much) but here is one issue:

If you asked somebody how far it was from here to the corner, and they told you 7200 inches, it probably wouldn't help you as much as if they told you the answer in feet or yards. Even if your answer is numerically right, even if you did the math perfectly, choosing appropriate units will make your answer more useful!
