Time for another puzzle. I found this one at a

puzzle site in the Netherlands. Despite having a Dutch web address, the site appears to be entirely in English.

Anyway, here's the puzzle:

I have a room that's 9 metres by 12 metres, and I'm going to have an 8 metre by one metre aquarium right in the middle of it (lengthways).

Quickly noticing that the area of open floor will be exactly 100 metres (9x12-8), I buy a 10 metre by 10 metre carpet that was going cheap on eBay. But how to cut it to fit the shape? I don't want to cut the carpet more than necessary. What's the smallest number of pieces I must cut the 10x10 metre carpet into, to make it fit the 12x9 space, with the 8x1 hole in the middle? Hint: It's less than four.

I've attached the picture of the situation take from the above web site.

if possible, please.

I hope this non-verbal, non-numerical, non-logic puzzle will make a nice change.
