Answer: 20 inches

Step-by-step explanation: Given that the area of the rectangle is equal to the area of the square (16), we can use the formula for the area of a rectangle: Area = length width. Substituting the values we have: 16 = 8 width. To solve for the width, divide both sides by 8: width = 16 / 8 = 2 inches. So, the width of Kelsey's rectangle is 2 inches. Now that we have the length and width of the rectangle, we can calculate the perimeter using the formula for the perimeter of a rectangle: Perimeter = 2(length + width). Substituting the values we have: Perimeter = 2(8 + 2) = 2(10) = 20 inches.
