For rectangles, we know that there are two of each measure (length and height). If the length is four times the width, then this means l = 4w. Because there are two of each, it becomes 2 * (4w), which represents the two length measures. Now we also have two width measures, which is 2w. The phrase 'at most' hints at to perimeter being greater than or equal to something.
The answer is [tex]2w + 2 * (4w) \leq 130[/tex]
