2 dm
2 km = 20,000 dm
10 dm = 1 m so 200 dm = 20m. 20 km is 1000 times as long. This is assuming "dm" = decimetres. If it = dekametres then 200 would be 2 km.
2 dm is two decimetres The metric deci- prefix means 1/10 (tenth or 0.1) ⇒ 2 dm = 2 x 1/10 m = 0.2 m

dm could be decimeters, which are 1 tenth of a meter
The volume of the box in cubic centimeters is 5000 cm³ (25 cm * 2 dm * 1 dm * 10 cm/dm). The volume of the box in cubic decimeters is 10 dm³ (0.25 dm * 0.2 dm * 0.1 dm * 1000 cm³/dm³).
1 dm = 1 cm → 1 dm² = 1 dm × 1 dm = 10 cm × 10 cm = 100 cm² → To convert dm² to cm² multiply by 100 → 5 dm² = 5 × 100 cm² = 500 cm².
By unit of length and distance and conversion ,we can say that 1 dm =10 cm 2 dm=20 cm hence ,2 dm >18 cm
1 dm = 10 cmso, (1 dm)2 = (10 cm)2 = 100 cm2
10 cm = 1 dm 20 cm = 2 dm
1 dm = 10 cm 1/5 dm = 2 cm
