If one measurement of a golden rectangle is 5.4 inches, which number could be the other measurement? a. 3.337 b. 7.018 c. 1.618 d. 3.782

A golden rectangle is a rectangle whose side lengths are in a golden ratio.
The golden ratio is:
1 : Φ which is approximately 1.618

Now, we are given that:
one side is 5.4 in
ration of sides is 1.618

This means that:
side1 / side2 = 1.618
5.4 / side2 = 1.618
1.618 side2 = 5.4
side2 = 5.4 / 1.618
side2 = 3.337 in

Based on the above calculations, the correct choice is:
a. 3.337
