Official Solution:


Statement (1) by itself is sufficient. The longer side of the rectangle is bigger than 2, thus the diagonal is bigger than \(\sqrt{2^2 + 2^2} = \sqrt{8} \gt \sqrt{6}\).

Statement (2) by itself is sufficient. The diagonal is bigger than \(3 = \sqrt{9} \gt \sqrt{6}\).


Answer: D

Each statement is in itself sufficient :

considering statement 1. shortest side is 2,hence longer side is at least greater than 2 ie diagonal greater than at least square root of 8 hence sufficient.

considering statement 2. longest side is 3,hence shorter can be anything but the diagonal is greater than at least square root of 9 ,hence sufficient.

I think this is a high-quality question and I don't agree with the explanation. Statement 1 : The shorter side is 2, hence the diagonal is longer than √(4+4) = √8. Since, √8 > √6, Sufficient.

Statement 2 : The longer side is 3, hence the diagonal is shorter than √(9+9) = 3√2. Since, 3√2 > √6, Insufficient.

No, that's not right.

For (2) if the longer side is 3, then the diagonal must be greater than \(\sqrt{3^2+ 0^2}=\sqrt{9}\).
