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.
