A:
Answer: option a. 5.46
Explanation:
The side lengths of the golden rectangle are in the proportion:
1 -------------------- golden number
The golden numbrer is:
1 + √5 ----------- 2
So, the ratio is:
1 -------------- 1 + √5 --------- 2
And, using the properties of the division of fractions, that is equivalent to:
2 ------------- 1 + √5
Since you have the given side t = 9, you can set the proportion, to find the unknown lenght, s:
