The difference between the length and the width of a rectangle is 5 centimeters.

23

Step-by-step explanation:

if the perimeter of the rectangle is 28, then we know that the two side lengths are equal to each other and the two widths are equal to each other.

we are given that a width is 5 cm. multiply 5 by 2. you will get 10. 66 minus 10 equals 56.

56 should be the sum of the two lengths. to get one side length, simply divide 56 by 2. you should get 28. so we have a 28 cm as the length and 5 cm as the width.

because they're asking you to find the difference between the length and width, 28 minus 5 equals 23.
