Answer 2

Calculation

To perform the calculation, we need to subtract 5 decimeters from 8 meters 4 centimeters, then add 2 meters 7 centimeters and 38 centimeters.

Solution

- Subtract 5 decimeters from 8 meters 4 centimeters: - 8m 4cm - 5dm = 8m 4cm - 50cm = 7m 54cm

- Add 2 meters 7 centimeters and 38 centimeters: - 7m 54cm + 2m 7cm + 38cm = 9m 99cm

So, the result of the calculation is 9 meters 99 centimeters.
