| **Calculate the perimeter of a rectangle in which the length of one side is 438 cm, and the length of the other side is 6 times less.**

To solve this problem, remember that the perimeter of a rectangle is the sum of the lengths of all its sides. Since in a rectangle the opposite sides are equal, then P = 2 * (a + b), where a is the length, b is the width. Let’s calculate what the width of the rectangle is.

438/6 = 146 centimeters.

Let’s calculate the perimeter of the rectangle.

P = 2 * (438 + 146) = 2 * 584 = 1168 cm.

Answer: 1168 cm.
