Answer:

C. 2 feet by 4 1/4 feet

Explanation:

One of the closet dimensions is 1 inch on the drawing. The scale tells you that represents 2 feet, so only choices B and C have that dimension correct.

If each inch on the drawing is 2 feet then 2 1/8 inches will be 2 1/8 times 2 feet:

(2 1/8)(2 ft) = 4 2/8 ft = 4 1/4 ft

This matches choice C: 2 feet by 4 1/4 feet.
