A scale drawing of an office building is not labeled but indicates 1 / 3 inch = 4 feet. On the drawing one wall measures 4 and 2 / 3 inches. How long is the wall?

Is it possible to find out how long is the wall? The choices shown for the problem are: (a) 8 feet (b) 12 feet (c) 14 feet (d) 15 / 9 feet (e) None of these.
Because I had put down (e) none of these. 
Cause i wasn't really sure

(1/3) / 4 = (14/3) / x
Cross multiply and solve for x. 
25 feet x 35 feet
