Is it 4, 4, 6?

A has L = 14, and B has Area = sqt(63).
1) A does not know answer because it could be 4, 5, 5 or 4, 4, 6.
2) B does not know answer, becuse it could be 4, 4, 6 or 2, 8, 8.
3) A know the answer, because the only 4, 4, 6 could confuse B.
4) B know the answer, because only the 4, 4, 6 has only two possibilities.
