Answer
$\frac{\sqrt 5+1}{2}\approx1.62$
Work Step by Step
With the given golden rectangles formula $\frac{w}{h}=\frac{2}{\sqrt 5-1}$, multiply the conjugate of the denominator $\sqrt 5+1$ to both the numerator and the denominator; we have $\frac{w}{h}=\frac{2}{\sqrt 5-1}\times\frac{\sqrt 5+1}{\sqrt 5+1}=\frac{\sqrt 5+1}{2}\approx1.62$
