My apologies to anyone who responded to this post earlier.  I was not quite ready to proceed as I didn't get around to measuring the walls in question.  

Two walls in a townhouse: powder room and master bedroom.  The wallpaper I purchased requires glue. The wall in the powder room behind the toilet measures approx 37" X 89"; the total surface is a little more than 23 square foot .  The sloping wall in the master bedroom is approx 16' wide and the height is 7.5' on the two ends and 10' at the highest point; total surface of about 140 square foot.
