Answer 2

If you aren't able to stick the planks together, its 42m, you can't add on to the 42m you have, so just cut off the others off 49 and 63 to get 42 on each.

If you are, well, it's a recurring number, being 52.33m, it would go on like 52.3333333m, until eternity, but nobody can type infinity, so you can round it down, or add a point like 52.33'
