| 1. Suppose that the length of the rectangle is x cm.

2. Since in the problem statement it is said that its width is 4 times less than its length, so we can write its length as x / 4 cm.

3. Let’s write the equation, solving which we find out what the length of the rectangle is, if we are given that the perimeter of this rectangle is 60 cm.

60 = 2 * x + 2 * x / 4;

60 = 2x + 2x / 4;

240 = 8x + 2x;

240 = 10x;

x = 240/10;

x = 24 cm.

4. Find out what the width of the rectangle is.

24/4 = 6 cm.

Answer: The width of the rectangle is 6 cm, the length is 24 cm.
