Passage: I asked someone at Home Depot about this since I 've never done it before . They were very helpful . They told me how to figure out how much wallpaper I would need . I had to measure how high they were and how wide they were . Then there was this formula where you multiplied the height times the width , divided that by 144 ... and that 's as far as I got . Wallpaper is n't that expensive and I did n't mind having some left over . I can always get more if I need it . I finally got everything out of my bedroom . Other than my bed , the room was totally empty . I opened the package and unrolled a sheet of wallpaper on the table . I peeled the backing off , climbed the ladder , aligned it with the ceiling and affixed it to the wall . Question: The tape measure will be used on what? Option1: The wallpaper Option2: Measuring the walls
Measuring the walls
