Answer 3

To convert measurements from decimeters (dm) to centimeters (cm), you need to know that:

1 decimeter (dm) = 10 centimeters (cm)

Now, let's convert the given measurements:

1 dm = 10 cm 2 dm = 2 * 10 cm = 20 cm

4 dm = 4 * 10 cm = 40 cm

So, the conversions are as follows:

2 decimeters (dm) = 20 centimeters (cm) 4 decimeters (dm) = 40 centimeters (cm)
