Area is the amount of space taken up by a shape. To find the area of a
rectangle you multiply the width by the height. Consider this rectangle:
This rectangle has a height of 13 units and a width of 14 units.
AREA = 13 x 14 = 182 square units
To help you to visualize this a little better consider this example:
As you can see this square contains 64 little squares. Each of these squares
is a square unit. Area is measured in square units. This square has an area
of 64 square units.
