Question 98084: This is a word problem that I was given and am having grief solving.
You have a carpet that measures 12' x 3' and you need to carpet an hallway that measures 9' x 4'. WITHOUT folding the carpet, how can you carpet the area with only making ONE cut.
This was a two part question. On the first part you were allowed to fold the carpet and I figured it out, but I cannot get this part. Perhaps making multiple cuts without taking your scissors off the carpet, but I can't get it to work. Any help would be appreciated. Thanks.
