The perimeter of the rectangle is 24cm. Its width is 4 times less than its length. Find the length and width of the rectangle.

1. Suppose that the length of the required rectangle will be x cm.

2. Since we know that the width of this rectangle is 4 times smaller, then it will be (x / 4) cm.

3. Let’s write down the equation and calculate the length of the given rectangle if we know that its perimeter is 24 cm.

x + x + x / 4 + x / 4 = 24;

4x + 4x + x + x = 24 * 4;

10x = 96;

x = 96/10;

x = 9.6 cm.

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

9.6 / 4 = 2.4 cm.

Answer: The width of the rectangle is 2.4 cm, the length is 9.6 cm.
