Four decimeters is longer than four centimeters since a decimeter is ten centimeters, thus 4 dm is 40 cm. Four centimeters is roughly an inch and a half while four decimeters is about the length of four cigarettes (100's).
Remember the mnemonic device: "Kids Have Dogs But Dogs Cost Money" or Kilo, Hecto, Deca, Base, Deci, Centi, Milli" So based off our mnemonic device cm is already less than dm. So therefore, 4cm < 4dm.
4 dm is greater than 400mm
4dm=400cm that's what i think but I'm not so sure.
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
