Step 1

To find the perimeter, we just need to add all the side lengths together. The picture below shows all the side lengths of the parallelogram:

Step 2

Let the perimeter be **P**. By adding all the side lengths, we have:

Step 3

Now, the calculated number, **22**, has no meaning unless we include the unit for it. Since the sides are in centimeter, the perimeter will also be in centimeter. Hence:

P = 22cm

Step 4

Clearly, the answer is A.
