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.
2000 meters.
1 dm2 = (1 m / 10 dm)2 = 1/100 m2 or 0.01 m2
If the question means how many miles is 600 km, the answer is 372.82 (to 2 dp).
1.67 miles.
20 decimetres = 2 metres.

2 km = 2,000 m
7.3 dm. a decimeter is = 10^-1 meters, a centimeter is = 10^-2 meters
500 m = 0.5 km = 1/2 km
2 m = 20 dm
3.218688 kilometers

2 kilometers equals 200,000 centimeters.
