A circle will will have the width of its diameter whichever way it really is rotated, as a result this would be the shortest width.

The shortest width of a square will be the length of a aspect. But think about the longest length? That can be found by measuring from top of the left-hand part to the lower-right hands corner. So today our focus can change to finding a condition whose longest size and shortest width are the same.
