6-4.

On grid paper:

• Draw a square that measures $5$ units on each side.

• Draw a design inside your $5×5$ square.

• Then draw a square that measures $15$ units on each side.

• Enlarge your picture as accurately as possible so that it fits inside of the $15 × 15$ square.

How much wider and how much longer is your new picture?

A simple design will be easiest to enlarge.

How much longer is a $15$ unit number line than a $5$ unit number line?
