The protagonist of the game Atelier Ryza: Ever Darkness & the Secret Hideout , Reisalin Stout, who wears red pants and shows off her legs and navel, has caught many people's eyes even before the game came out. Now we're looking for a way to estimate her height.
To make her look pretty, the designer had to carefully decide the ratios. Assume that the ratio of the length from her navel to the bottom of her feet and the length from the top of her head to her navel is equal to golden ratio . Besides, the ratio of the length from her throat to her navel and the length from the top of her head to her throat is also equal to .
Given that her legs are long and the length from the top of her head to her bottom of her neck is , which could be a possible height for Reisalin Stout?

. We're sorry about the hassle.
If her legs are 9 5 cm long, which is smaller than the length from her navel to the bottom of her feet, and the ratio of the length from her navel to the bottom of her feet and the length from the top of her head to her navel is ϕ , then the length from the top of her head to her navel must be greater than ϕ 9 5 , so that her whole height h is h > ϕ 9 5 + 9 5 = 9 5 ϕ or h > 1 5 3 cm .
If the length from the top of her head to her bottom of her neck is 2 4 cm long, which is greater than the length from the top of her head to her throat, and the ratio of the length from her throat to her navel and the length from the top of her head to her throat is ϕ , then the length from her throat to her navel must be smaller than 2 4 ϕ , which makes the length from the top of her head to her navel smaller than 2 4 ϕ + 2 4 , and since the ratio of the length from her navel to the bottom of her feet and the length from the top of her head to her navel is also ϕ , then the length from her navel to the bottom of her feet is smaller than ( 2 4 ϕ + 2 4 ) ϕ , so that her whole height h is h < ( 2 4 ϕ + 2 4 ) ϕ + ( 2 4 ϕ + 2 4 ) = 2 4 ( ϕ + 1 ) 2 or h < 1 6 5 cm .
Therefore, 1 5 3 cm < h < 1 6 5 cm , and the only choice that fits this criteria is 1 6 1 cm .
