Find the perimeter of a rectangle that is 14 cm long, which is 5 cm more than its width.

To solve the problem, you first need to find the width of the rectangle.

Since it is 5 cm longer than the width, you need to subtract the difference from the length value.

We get:

14 – 5 = 9 cm (rectangle width).

The perimeter is twice the sum of the sides of the rectangle.

In literal form, this expression can be written as follows:

P = 2 * (a + b).

Substitute the known values into the formula and get:

P = 2 * (14 + 9) = 2 * 23 = 46 cm.

Answer: The perimeter of the rectangle is 46 cm.
