The Golden rectangle is a rectangle in which one side is approximately 0.618 times the other side.
0.618(...) This is the "Golden Number". It is the only number whose inverse is itself plus one: 1/x=x+1. If you solve this quadratic equation you will get x1=[1+sqr(5)]/2=0.618... and x2=1.618....
This number is also the ratio at which the rabbits reproduce, which follow the so called Fibonacci series: 1, 1, 2, 3, 5, 8, 13, ... in which a number is the sum of the 2 previous numbers (the next number in the example is 8+13=21). The Golden number is obtained by dividing one of these numbers into the immediately next number. For example, 13/21=0.619, but if you do this with bigger numbers you will get the exact value.

A golden rectangle is a rectangle whose side lengths are in the golden ratio, approximately 1:1.618. A 3x5 card has side lengths of 3 inches by 5 inches, which do not match the golden ratio. Therefore, a 3x5 card is not a golden rectangle.
