Arithmetic Grade Five

Lesson One hundred and forty-four: Area

Here's another rectangle for you to take a look at.

As you can see it has a height of 5 units and a length of 24 units. 


    AREA = 5 x 24 = 120 square units
Remember units can be inches, feet, yards, meters, or any other unit of length. We use the term units when the actual unit is left unspecified.
