Length - Applying Length

In the previous posting, you have learned about length. Now you will about units of length and how to apply them.

The units of length in this topic are: Meter (m), Centimeter (cm)

1 Meters (m) = 100 Centimeters (cm)

To convert an object with 3 meters of length into centimeters, you just need to multiply the number (in this case, 3) with 100. For example:

A length of a 'wau' is 1 meter. How long is the length of it in centimeters?
1m X 100 = 100cm

So, the 'wau' is 100 centimeters in length.


Now you try:

Imagine Ruler A is 1 meters long. Ruler B is half of the length of Ruler A. Ruler C is 30 centimeters.Between Ruler B and Ruler C, which one is longer?

Answer:

Ruler A is 1 meters long.
Ruler A: 1m X 100 = 100cm

Ruler B is half the length of Ruler A.
Ruler B: Length of Ruler A ÷ 2
Ruler B: 100cm ÷ 2 = 50cm

Ruler C is 30cm long.

So Ruler B is 50cm, Ruler C is 30cm.

Ruler B is longer.

That is all for today. Thank you.
