Solution.
L = 4w --------The length of a rectangle is four times its width.
2w + 2L ≤ 130 ------- the perimeter is at most 130 centimeters.
Now, if substitute the first equation into the second inequality you will get
2w + 2 • (4w) ≤ 130.
Therefore, the inequality model in C is correct.
Bonus.
If you solve the inequality you will have a final answer w ≤ 13. The greatest value being 13.
Hope it helps,
