Solution
The correct option is A 18 cm
Given ABCD is a parallelogram, with two adjacent sides AB and BC being 6 cm and 3 cm respectively.
Since the opposite sides of a parallelogram are equal So,
AB= CD = 6 cm and BC = AD = 3 cm
Now, perimeter = sum of all sides of the parallelogram
⇒ Perimeter = AB + BC + CD + AD
⇒ Perimeter = 6 + 3 + 6 + 3
⇒ Perimeter = 18 cm
