Answer 3

To add these measurements, you need to make sure they are in the same units. In this case, it appears that you have measurements in centimeters (cm) and decimeters (dm). To add them together, you should convert everything to the same unit. Let's convert everything to centimeters:

15 cm + 5 dm 8 cm + 2 dm 17 cm + 8 cm

1 decimeter (dm) is equal to 10 centimeters (cm), so:

5 dm = 5 * 10 cm = 50 cm 2 dm = 2 * 10 cm = 20 cm

Now, you can add the measurements together in centimeters:

15 cm + 50 cm + 20 cm + 17 cm + 8 cm

Add the values:

15 cm + 50 cm + 20 cm + 17 cm + 8 cm = 110 cm

So, the sum of these measurements is 110 centimeters.
