The length of the rectangle is 28 cm and the width is 9/14 of its length. Find the perimeter of the rectangle.

The length of the rectangle is 28 cm.

The width of the rectangle is – 9/14 of its length.

Let’s define the perimeter of this rectangle. We write down the resulting solution.

First, you need to determine the width of this rectangle.

28: 14 * 9 = 18 cm.

Therefore, the width of the rectangle is 18 centimeters.

Next, we define the perimeter of this rectangle. To do this, fold all the sides of the rectangle. We write down the solution.

P = 2 * (a + b).

P = 2 * (28 + 18) = 2 * 46 = 92 cm.

Answer: The perimeter of the rectangle is 92 centimeters.
