Question

using only 7 of the pentomino puzzle pieces(V.P.W.Z.T.L.Y)

is it possible to create a 5 by 7 or 7 by 5 rectangle?

you are allowd to flip the pieces or turn them

5 by 7 equals 35 so 7 shapes 5 pieces each is 35

mathmatically its possible but physically?

i have tried over 5hours in past 2weeks but never got it

I have no idea what a petomino piece is so I have no idea how to start thinking about this puzzle. It would help if you could explain. Explaining what a petomino peice is might also help other people with this puzzle. xx

I got it, assuming that I can reuse the same pieces...

Make a rectangle 7 units wide by 5 tall.

I broke it up into three parts:

1) Make a 3x5 (I used either a Y, T, and L or P, P, and L

2) Make a 2x5 (P and P)

3) Make a 5x2 (P and P)

Stack the 3x5 on top of the 2x5, giving a square 5x5. Stack the 5x2 on any side of the square to make 7x5 or 5x7.

As easy as that was, I'm going to assume now that I can't reuse the same shape...

To the drawing board? I'm using sticky notes.

There are over 2000 ways of doing this, I've heard.

A while ago we tried to find (some of) those and kept track on the solutions by drawing them on paper.

Hmmm...I'm sure there are many ways to do it with all pentominoes, but I don't think there are 2000 ways to do it using only the pieces provided in the OP.

You can't cover 5 by 7 grid with V.P.W.Z.T.L.Y tiles.

If you use all twelve then there is exactly 5584 solutions but

if you want to use those particular seven then there is no way to

complete the puzzle.

How do I know this ?

Below is two helpful links to pentomino related sites:

http://math.hws.edu/xJava/PentominosSolver/ This is Pentomino Puzzle Solver.

http://www.pentomino-puzzles.com This is application to play games

based on pentomino tiles.
