Can someone please help me? I’m having trouble with this rotation question (question 14 a, b, and c)

In order to make it a golden rectangle, the two sides should be in golden proportion so the longer side should be 0.618 times the shorter one. so if the given side is the shorter one, the longer side should be about 6.472 inches and if the given side is the longer one, then the shorter one should be about 2.472 inches
