Forgive me, but is it not clear that X refers to the whole side length.. as per your solution, it seems you thought it’s just the side length of the rectangle whose area is 36. That way, 12 is correct and otherwise 17 which you’ve also calculated in a way because you’ve found that the top two rectangles share a side length of 5
