8 + 5 = 13

13 + 5 = 18

soldier1979 [14.2K]

Let w be the width and l the length of the rectangle.
Then: $\frac{l}{w}= \frac{1+\sqrt5}{2} \text{ and }lw=104$
Solving the above system we get:
$l= \frac{1+\sqrt5}{2}w\\= \frac{1+\sqrt5}{2}\frac{104}{l}$
Therefore:
$l^2=\frac{1+\sqrt5}{2}104$ then $l=13$ ,which is the length,
And then the width $w=\frac{104}{13}=8$
