Question

Melissa planted a sapling in her garden. She measured its height with a ruler. The tree was 15 centimeters tall. After a week, she measured it again. This time, the tree measured 25 centimeters. How many millimeters did the tree grow? The tree grew millimeters in a week.

Answer 1

25 cm - 15 cm = 10 cm

Now to convert to millimeters just multiply by 10

Your correct answer is 100 mm

Answer 2

100 Millimeters

Step-by-step explanation:

The tree's first measurement = 15 centimeters

The tree's measurement after a week =25 centimeters

The difference in growth = 25 - 15 = 10 cm

Since we are asked to find out how many millimeters the tree grew, we convert our result to millimeters.

Conversion Unit: 1 centimeter = 10 Millimeters

Therefore: 10 cm = 10 X 10 =100 Millimeters

The tree grew 100 Millimeters in a week.
