Hopefully !

Spoiler:

Cut a 1 * 10 slice from one edge of the carpet and from one end of this slice remove 1 * 1 >> 2 pieces [ 1 * 9 & 1 * 1 ]

Cut a 1 * 8 piece into the middle of the remaining 10 * 9, from one of the shorter edges >> 1 large "U" shaped piece.

Lay the 1 * 8 piece to close off the "U" and add the 1 * 1.
Lay the 1 * 9 to complete.

3 pieces cut....
