Final answer:
Sam's tree that was originally 0.53 meters tall grew to be 100 times taller over 10 years, making it 53 meters tall after that period.
Step-by-step explanation:
Sam found a tree that was 0.53 meters tall. After 10 years, the tree was 100 times as tall as when he first found it. To find out the height of the tree after 10 years, we simply need to multiply the initial height by 100.
0.53 meters (initial height) × 100 = 53 meters.
Therefore, the tree's height after 10 years is 53 meters.
