This scenario was easy because only one of the answers resulted in a perfect square, so the others were eliminated. If you would have come up with 2 answers that were perfect squares, such as 196 and 225, then you'd have to look further.

The number added to 132 resulting in 196 or 225 would have to be a perfect square as well because we're told the interior patio is square. From that standpoint, 64, 81 and 100 were options, but only 64 + 132 = a perfect square (196 = 14^2)
