See attached as this is easier to show both with a diagram and with correct mathematical notation.

Answer = 16.

gaggleofgirls,

thanks for the solution attachment. However, you lost me when you factored out 16 from the numerator. when you factor out 16 from "16 square root 2," only "square root 2" should remain, but you have a "2 sqare root 2" still.

typo? or am i not getting something. :) <== which happens all the time!

thanks,

Just a typo. I have replaced the file with an updated one. Yes, when you factor 16 out of (16*sqrt2 + 32) you get 16(sqrt2 + 2) which is what you need to cancel out the denominator.
