# Challenging 15 rectangle tiling problem

This will test you, a computer will definitely help. Just one set of $1:2$ aspect ratio rectangles this time, but $15$ of them. Short side only is listed. The challenge is to arrange them into a square with no gaps or overlaps. There are several sets of sub-rectangles which can be rotated/flipped to give eight tilings.

1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 18, 19, 25

I tagged it both computer-puzzle and no-computer because I'm pretty sure there are people out there who could hand-tile this.

• Why use both tags? Removing them implies the same thing.

• Not really... adding a computer tag to a riddle would make no sense and adding no-computer to a riddle would be superfluous. But adding both to this puzzle has meaning. If you are following computer puzzles you would want to see this, just as you might want to see it if you are into hand tiling puzzles. Jan 18, 2018 at 14:16
