The sides of the parallelogram are pairwise equal. (let’s say AB = CD, a BC = DA). Since the perimeter is 46 cm, and the sum of the three sides is 32 cm, then one of the sides is equal to: 46-32 = 14 cm. Consequently, the other side is also equal to 14 cm. It remains 32-14 = 18 cm on two equal sides. Dividing by 2, we get the length of the other side: 18: 2 = 9 cm.
Answer: two 9 cm and two 14 cm.
