Hi, this question is from big book test 5 section 6 question 4. Can someone explain why the answer is A? do we just assume this by looking at it?

@Leaderboard can you help please!!

Not necessarily assume, but kind of. You can even take the extreme case (i.e, when it’s inscribed) and show that the perimeter of the square must be greater than the rectangular region.

Is this how I can take an extreme example? And since the above is NOT inscribed, Perimeter will be even less? is that a concept?

Yes, and that can be deduced by inscribing a smaller square on that (smaller) rectangle.
