Problem:

I want to wallpaper a 10' x 12' room that has 8' ceilings. The wallpaper has 44 sq. ft. per double roll.

How many double rolls of wallpaper do I need to order? (Wallpaper is not available in single rolls.)

Solution:

Width x Height square footage	= # of double rolls needed
44 sq ft x 8 feet 44 sq ft/roll	= 8 rolls

...OR add the area of each wall

[2 (10 x 8) + 2 (12 x 8) ] = 352 square feet

352 sq ft 44 sq ft/roll

= 8 double rolls
