Better Solution for Puzzle 076 "A Tile Square"

I have found a better solution to Puzzle 076, "A Tile Square", in Professor Layton and the Curious Village.

One of the hints says that "you'll need to do a little creative thinking in order to find the fewest number of tiles that allow you to 'FORM A SQUARE'."

Well, I have found a way to "FORM A SQUARE" several ways "creatively" using only FOUR tiles, not the answer given in the game, which is much higher (no actual spoilers here).

With the tiles laying flat as in the picture shown for the puzzle description, if you take one tile and butt it up against another tile at a right angle so that a 12-inch side is in line with the other tile's 10-inch side, (makes an "L" shape) and repeat this for the second and third tiles, and third and fourth, so that the fourth butts up against the first tile in a similar manner, you will end up with a 2-inch-by-2-inch SQUARE hole in the center, AND an outer SQUARE perimeter of the whole group with 22 inches on each side. Even the tiles themselves form a square.

Likewise, you could turn all 4 tiles up on one end (say, all 12-inch-by-0.5-inch sides down), so that when you look directly down on the tiles, you see four 12-inch-by-0.5-inch sides. You can arrange the tiles in the same manner as above to get a central square that is 11.5 inches on a side, and an outer perimeter square that is 12.5 inches on a side.
