# Measuring lengths with different units

Use different units to measure the same object.

## Measuring lengths with different units

Let's measure a fence with squirrels!

The fence is 10 squirrels long.

Now let's measure the

**same**fence with ponies.The fence is 5 ponies long.

### Practice problem 1

This is a rectangle.

Let's measure the start color #11accd, start text, b, l, u, e, space, l, i, n, e, end text, end color #11accd below using both rectangles and a centimeter ruler:

### Practice problem 2

### Challenge question

## Want to join the conversation?

- On practice problem one, why did it ask about the width of the rectangle when it should've asked the length. Clearly the width was the same as a centimeter, and the length was shorter. When I answered shorter it said correct.(107 votes)
- The width is on the bottom, the length is on the side, that is why it is width(41 votes)

- can a pony be longer than a squirrels?(8 votes)
- Yes, the pony will be longer then a squirrel because the squirrel is shorter then the pony(4 votes)
