The length of a rectangle is less than one decimenre per 2 cm, which is equal to the width

The length of a rectangle is less than one decimenre per 2 cm, which is equal to the width of this rectangle if the sum of the lengths of its sides is 24 cm.

To solve this problem, you first need to determine the length of the rectangle.

1 dm = 10 cm.

1 dm – 2 cm = 10 cm – 2 cm = 8 cm.

Therefore, the length of this rectangle is 8 centimeters.

Next, we define the width of this rectangle.

The perimeter of a rectangle is equal to the sum of the lengths of all sides of the rectangle. Let’s write down the formula.

P = 2 * (a + b).

c = (P – 2a) / 2.

c = (24 – 2 * 8) / 2 = (24 – 16) / 2 = 8/2 = 4 cm.

Therefore, the width of the rectangle is 4 centimeters.

Answer: the width is 4 cm.
