200 centimeters=20 decimeters
4 dm is greater than 400mm
18.3 dm is longer.
1 km = 10 dm

4 dm
To find the area of a square, you multiply the length by the width. In this case, 200cm x 200cm equals 40,000 square centimeters. To convert this to square meters, you divide by 10,000 (since there are 10,000 square centimeters in a square meter). Therefore, 40,000 square centimeters is equal to 4 square meters.
Km
200cm = 2m ...
2000 dm is the same as 200 m. 2000 dm is longer than 20 m, not bigger.
Certainly, 70 dm is longer than 6 m by 10 dm.
The conversion between cm and dm are given .On finding the relation we get as follows . 1 dm=10 cm . It means decimeter is longer than cm.
