Question

Suppose a greeting card is 4 inches long on one side. About how long should the other side of the card be in order for it to be a Golden Rectangle?

Answer 1

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
