Let the length of the rectangle L = 18 dm, then the width W = D – 17.

It is necessary to calculate the perimeter of the rectangle.

First, we find the value of W.

W = 18 dm – 17 dm = 1 dm.

Now we will use the formula for determining the perimeter of P.

P = 2 * (L + W).

Let’s make the substitution and calculate.

P = 2 * (18 + 1).

P = 38 dm.

Answer: the perimeter of the rectangle is 38 dm.
