MO and OR and the diagonal MR are three lengths of a triangle; and we do not know the angle at point R, but we can find it using Law Of Cosines.

5%5E2%2B3%5E2-2%2A5%2A3%2Acos%28r%29=6%5E2
25%2B9-30%2Acos%28r%29=36
-30%2Acos%28r%29=0
cos%28r%29=0
r=pi%2F2 a right angle.

This is simply a RECTANGLE, 5 cm by 3 cm.
