One hundred sixty eight square feet of carpet has been ordered for a 12 foot wide room. How long should the room be?

Area = (length) x (width)

168 square-feet = (length) x (12 ft)

Divide each side by 12-ft : (168 sq-ft) / (12-ft) = length

14-ft = length.

Since the carpet has already been ordered and the order

can't be changed, if the room is not 14-ft long, then the

room must be either cut down or added onto.
