sure cause some are meters and some are centimeters

deadly_roses · Answer

yes it would be m

deadly_roses · Answer

1.09m is your answer

sushi121212 · Answer

The answer is D because you would have to transform the 31 cm into meters. That would leave you with 0.31 m. Then, you add those together:

0.31 + 0.33 + 0.45

That leaves you with 1.09 m because the unit is in meters.
