The ratio of the length to the width of a rectangular advertising display is approximately 3.3 to 2. If the width of the display is 8 meters, what is the approximate length of the display, in meters?

(A) 7

(B) 11

(C) 13

(D) 16

(E) 26

Let’s first set up our ratio using variable multipliers.

length : width = 3.3x : 2x

We are given that the width is 8 meters, so we set up the following equation:

2x = 8

x = 4

Thus, we know that the length is (4)(3.3) = 13.2 meters.

The closest answer is 13.

Answer: C
