- The height of a particular tree is increasing at the rate of 10 cm per month. What
would be height of the tree after 5 years if its present height is 10 m?
[Hint: Assuming the growth of the tree is uniform.]



Answer :

Height of the tree after 5 years would be: 16 meters.

Starting height = 10 m

Rate of growth = 10 cm per month

Convert 10 cm per month to meter per year.

10 cm / 1 month

10 cm = 0.1 m

1 year = 12 months

0.1 × 12 = 1.2

1.2 meters per year

Duration: 5 years

5 × 1.2 = 6

6 meters in 5 years

6 + 10 = 16

Thus, the height of the tree after 5 years if its present height is 10m, is 16 meters.
