Rashad wants to wallpaper the four walls of his bedroom. the room is rectangular and measures 11 feet by 13 feet. the cieling is 10 feet high. a roll of wallpaper at a store is 2.5 feet wide and 50 feet long. how may rolls should he buy?

• 13ft X 10ft = 130 ft squared (but you have 2 walls with these demensions) so in total its 260 ft squared.
  
  11ft X 10ft = 110 ft squared (but you have 2 walls with these demensions) so in total its 220 ft squared.
  
  In total, 260 + 220 = 480 ft. squared.
  
  
  Set this equal to (2.5ft)(50ft)(X).
  
  So 1.25X = 480
  
  X=3.84
