Well, yes, but I'm not sure what to do when I only have one chord. I know CE and DE are congruent. And AE X BE = CE X DE, right? How do you get six square roots of two??
***EDITED: ohmygoodness I had the biggest blonde moment ever. I knew what to do and and I had all the work and just forgot to simplify the radical. Thank you so much for cooperating. Wow.... Yes, the square root of seventy two is six square roots of two.
