its a bitch to layout the reasoning, but confident its correcto
I made a mistake by writing (ab)^2 instead of (a+b)^2, silly mistake.
"Easy" solution is to use the fact that there IS an answer (otherwise it wouldn't be a question) and rotate 90 degrees by setting the rectangles to be x by 0, and 0 by x. Their area is now 0 and the remaining grey area is 14 by 14 so 196. Proving that this is the area for all rotations is harder.
