| To solve this problem, we introduce a conditional variable “X”, through which we denote the width of the rectangle. Then, according to the conditions of the given problem, we will compose the following equation: X = 8 x 40% / 100%. Solving this equation, we get X equal to 3.2 centimeters. Therefore, the perimeter of the rectangle will be 3.2 + 3.2 + 8 + 8 = 22.4 centimeters.

Answer: The perimeter of the rectangle is 22.4 centimeters.
