Final answer:
The width of the rectangle is 5 inches and its length is 7 inches.
Step-by-step explanation:
The given equation 2x + 2(x + 2) = 24 represents the situation with a rectangle's length being 2 inches more than its width and the perimeter of the rectangle being 24 inches. To find the value of x from the set {1, 3, 5, 7} that holds true for the equation, we can substitute each value into the equation and solve for x. By trying each value, we find that x = 5 holds true for the equation.
Therefore, the width of the rectangle is 5 inches and since the length is 2 inches more than the width, the length would be 7 inches.
