I just finished this project myself---OK if you are doing this DIY---what I did was make a template/pattern of my floor, I got a roll of craft paper or you can get the white light weight poster board from the dollar store and I cut strips the same size as my floor in the sections with the turns, I made sure to number the template pieces so that I could transfer them to the actual flooring piece to cut them out, this worked awesome for me my hall is straight for 34" wide x 130" long, then it turns at the end and gets all angled and in and out due to the 3 bed room doors then straight again, but I got it done, looks great too! Could send pics if you need.
