The Triplication Problem

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 right-hand corner is the V-pentomino 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. |
