Answer:

Step-by-step explanation:

1/3 = 0.333333

Set up a proportion.

0.333333/6 = 3.5 / x          Cross Multiply

0.333333x = 6*3.5             Multiply the right

0.333333x = 21                   Divide by 0.333333

x = 21/0.333333                

x = for all intents and purposes, the bookshelf is 63 feet long.
