Question

If you have a wooden board that is 0.75 meters wide, how long should you cut it such that the Golden Ratio is observed? Use 1.618 as the value of the Golden Ratio. 

I just multiplied them, but online sources have different answers.

My answer: 1.2135 m

Other answer: 0.4635 m

Answer 1

1.618x = 0.75

x = 0.464

0.75 - 0.464 = 0.286

Check:

0.286 / 0.464 = 0.6163

Answer 2

both answers are true

.75(1.618 or .75/1.618)

both make the ratio of one side to the other side = the golden ratio

just .75 being the larger in one and the smaller in the other

1.2135/.75 = 1.618

..75/.4635 = 1.618
