Answer :

A) From the given graph , we can say that , the height at the age of 5 years is 100cm.

B) From the given graph , we can say that , the height of the child at the age of 6 years is 110cm, and the height of the child at the age of 10 years is 130cm.

∴ we can say that the child of age 10 years is taller by 20cm from the child at the age of 6 years.

C) From the given graph , we can say that , between 2 and 4 years the growth in height of the child is of 15cm and between 2 and 4 years the growth in height of the child is of 20cm , so we can say that the 2 consecutive periods between which the child grow more faster were 2-4years and 4-6 years.
