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
