The width of a rectangular dance floor is w feet. The length of the floor is 6 feet longer than its width. Which of the following expresses the perimeter, in feet, of the dance floor in terms of w?
Correct answer: B. 4w + 12
- A. 2w + 6
- B. 4w + 12
- C. w2 + 6
- D. w2 + 6w
Explanation
Choice B is correct. It is given that the width of the dance floor is w feet. The length is 6 feet longer than the width; therefore, the length of the dance floor is w + 6. So the perimeter is w + w + (w + 6) + (w + 6) = 4w + 12.
