Read the following SAT test question, then click on a button to select your answer.

In the figure above, the large rectangle is divided into six identical small squares. If the perimeter of the large rectangle is 30, what is the perimeter of one of the small squares?

A. 5
B. 8
C. 9
D. 10
E. 12

Correct Answer: E

Here's Why:
The perimeter of one of the small squares can be found if you know the measure of one of its sides. So let s be the measure of a side of one of the small squares. Then the perimeter of the large rectangle is equal to 3s + 3s + 2s + 2s = 10s. Since you know that the perimeter of the rectangle is 30, you know that 10s = 30. So s = 3. Therefore, the perimeter of one of the small squares is 4 × 3 = 12.
