1. Let’s calculate the sum of the two sides of the parallelogram of length 16 cm.
16 + 16 = 32 cm.
2. Since the perimeter of a parallelogram is the sum of the lengths of all its sides and it is equal to 72 cm, and we also know the sum of the lengths of its two sides, we calculate the sum of the lengths of its other two sides.
72 – 32 = 40 cm.
3. Now let’s calculate the length of one unknown side.
40/2 = 20 cm.
Answer: The lengths of the other two sides of the parallelogram are 20 cm.
