Question

What will be the total length of four roads
which are 37 km 419 m, 24 km 75 m, 194
hm 307 dm and 5 km 6 hm 25 dm?
​

Answer 1

37000m+419m = 37419m....(1)

24000m+75m =24075m......(2)

19400m + 3070 m = 22470m....(3)

5000m+600m+250m= 5850m....(4)

now add (1),(2),(3),(4)

here , 1 hecto meter (hm)= 100m

and 1 deka meter(dm) = 10m
