Perimeter

This video is a companion to the area video. Area and perimeter are often confused. Hopefully using the smartboard to teach these concepts will clear up any miscommunication.

How to do it.

1. Capture the problem with the capture tool or type it in with the diagram.
2. Lock it down.
3. Make another line and label the length.
4. Use the order feature to bring it to front.
5. Now it can be moved and turned to form a line. This line is the perimeter of the distance around a polygon.
