To find the missing length of a rectangle, we need to know which dimension is missing. If the rectangle has a width of 8 inches and a perimeter of 60 inches, we can use the formula for the perimeter of a rectangle, which is ( P = 2(\text{length} + \text{width}) ). Rearranging the formula for length gives us ( \text{length} = \frac{P}{2} - \text{width} = \frac{60}{2} - 8 = 30 - 8 = 22 ) inches. Thus, the missing length is 22 inches.
