Lesson List


 

The Area of a rectangle or square is the number of square units it takes to cover the polygon.  To find the area of a rectangle, multiply the length times the width or L X W = Area.  To find the area of a square multiply side times side or S X S = Area.

Look at the rectangle below.

The L = 9 and the W = 4

9 X 4 = 36

The area is 36 square units.

 

Look at the square below.

The S = 5

5 X 5 = 25

The area is 25 square units.
