In similar rectangles, the corresponding sides are proportional. Therefore, we can set up the following proportion:
CD / BC = FG / GH
Plugging in the given values, we get:
36 / 12 = s / 9
Simplifying the left side of the equation, we have:
3 = s / 9
To solve for s, we can cross multiply:
3 * 9 = s
27 = s
Therefore, the value of s is 27 meters.
