A rectangle has a length that is four times its width. If the perimeter of the rectangle is 60 units, what are its dimensions?

Let's say the width of the rectangle is represented by x units. Since the length is four times the width, the length would be 4x units. The perimeter of a rectangle can be found by adding the lengths of all four sides, so we have: 2(4x) + 2x = 60. This simplifies to 8x + 2x = 60, which further simplifies to 10x = 60. Finally, dividing both sides by 10, we find that x = 6. Therefore, the width of the rectangle is 6 units and the length is 4 times that, which is 24 units.
