Math

### Lesson Excerpt:

Take your rulers and measure your desks or tables.  What is the length in inches? What is the width?  These are linear measurements.

Area is measured in square units – square inches, or square feet, or square yards, or square miles.  Let’s see how it is done.  A rectangle (or a square) is the easiest shape to work with.   Before you carry on reading go to Activity A.

There should be 24 square inches in the rectangle in the Activity – this is the area of the rectangle.
