Putting My Nerd Hat On

Can anyone come up with a neater solution method then the one I came up with (using Heron's formula) that froze up my TI-89 calculator?

Look at all those itty-bitty numbers. And just one variable. How tough can it be?

UPDATE: After drinking a couple cups of coffee and shaking loose the cranial cobwebs, I sat down and started from scratch. Ended up taking me maybe an hour to get it, without having to use a calculator (unless I wanted the answer in decimal form).

I'll post the solution in a minute. There was a typo on it.
