Correct Answer - Option 1 : 34 cm

**Given:**

First side of parallelogram = 6.8 cm

Other side = 3/2 × First side

**Formula used:**

The perimeter of parallelogram = Sum of all sides = 2 × (Sum of adjacent sides)

**Calculation:**

Other side = (3/2) × (6.8) = 10.2

Perimeter of parallelogram = 2 × (6.8 + 10.2)

⇒ Perimeter of parallelogram = 2 × 17 = 34

**∴ Perimeter of parallelogram is 34 cm**
