Cleave Books Pentominoes The Triplication Problem
To work on this problem, select any ONE of the pentominoes and set it apart from the rest.
Then, using 9 from the 11 pentominoes remaining, make a shape which is the same as the originally selected pentomino only 3 times bigger.
In the example on the right, in the top righthand corner is the Vpentomino which was the one selected.
Also shown is another V made from 9 pentominoes and
which is 3 times bigger in its dimensions than the original.
(Note that it is 9 times bigger in area.)
The X and N pentominoes were not used. 

9. 
Try triplicating any one of the other pentominoes.


Try the lot!
