Final answer:
To find the perimeter of a rectangle when its width is 8 inches shorter than its length, substitute the length and width values into the perimeter formula.
Step-by-step explanation:
The width of the rectangle is 8 inches shorter than its length. Let's assume that the length of the rectangle is x inches. Therefore, the width of the rectangle will be x - 8 inches. The perimeter of a rectangle is calculated by adding the lengths of all sides. In this case, the two lengths are equal to the length of the rectangle, and the two widths are equal to the width of the rectangle. The formula for the perimeter of a rectangle is P = 2L + 2W. Substitute the values of x and x - 8 into the formula and solve for P.
