jdoe0001 · Answer

PQ=QR, PQ=SP, that means is an square

jdoe0001 · Answer

so, the so-called 45-45-90 rule, the one in the picture above

mathstudent55 · Answer

You havn't done anything wrong. I was just trying to tell you that the key to this problem is the fact that those two statements let you conclude something about this rectangle that is essential to answering the question.

jdoe0001 · Answer

then the sides will be equally $\large whatever\times \frac{\sqrt{2}}{2}$
