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
