## Measuring

### Length

• Length is the distance from one point to another.

Also, we know length is involved when people ask questions such as:

How long is...?

How wide is...?

What is the height of...?

How tall are you?

How far is it to...?

Knowing about length is important to measure the size of stock yards, buildings, fences and distances between places.
