Peter wallpapered a wall that was 9 feet wide and 8 feet high. He had 27 square feet of wallpaper left over. How many square feet of wallpaper did he start with?

99 square feet

Explanation:
1.) Find the area of the wall:
8 feet x 9 feet = 72 square feet

2.) To find out how many square feet of wallpaper he had at first, add the area of the wall to the wallpaper he has left:
72 square feet + 27 square feet = 99 ft2
