You still don't see a square ? Well what do you see ? A four ? That is the answer !!! A little bit of mathemathic to understand this solution... 2²=4 so 4 is the square of two... Yes I admitt it was a tricky one, but Thibault and Charlotte found it...
If you managed to find this, congratulations, it wasn't easy at all !!
