17 meters

Step-by-step explanation:

Given: Jennifer planted a tree that was 0.17 of a meter tall. After 10 years, the tree was 100 times as tall as when she planted it.

To find: Height of the tree after 10 years.

Solution:

When the tree is planted, the height of the tree is 0.17 meter.

It is given that after 10 years the tree was 100 times as tall as when it is planted.

So, to find the height of the tree after 10 years we need to multiply 100 and 0.17

Now,

Hence, the height of the tree after 10 years is 17 meters.
