| In order to find out the perimeter, we first need to know the width of the specified shape. If the length of the rectangle is eight centimeters longer than its width, then the width of this figure is eight centimeters less than its length. Let’s find the width:

23 cm – 8 cm = 15 cm – is the length.

Let’s find the perimeter, remembering that this is the sum of all four sides of the rectangle (without performing multiplication):

P = 23 cm + 23 cm + 15 cm + 15 cm = 46 cm + 30 cm = 76 cm.

To summarize: the perimeter is seventy-six centimeters.
