In a parallelogram, the lengths of the opposite sides are equal. Let the smaller side of the parallelogram be X cm, then the larger side is 3 * X cm.
The perimeter of the parallelogram is: P = 2 * (X + 3 * X) = 40.
8 * X = 40.
X = 5 cm.
Then the large side is 3 * X = 15 cm.
Answer: The sides of the parallelogram are 5 cm and 15 cm.
