54m or 540dm

230cm or 23dm

1km or 10000dm

15dam or 1500dm

$\huge {\mathfrak {\green {\fcolorbox {red}{purple}{Answer:}}}}$

Now, let's add'em

(540 + 23 + 10000 + 1500)dm

= (2040 + 23 + 10000)dm

= (2063 + 10000)dm

= 12063dm [Ans]

1km = 1000m = 1000000mm

1hm = 100m = 100000mm

1dam = 10m = 10000mm

1m = 1m = 1000mm

1dm = 1/10m = 100mm

1cm = 1/100m = 10cm

1mm = 1/1000m = 1mm

Hope this helped...
