Finding the area of basic figures to include triangles and rectangles are a must know for algebra students. Remember that you will be using formulas so watch out for errors with the order of operations, positive and negative numbers and powers.

Some key concepts to remember about area and volume:

* area is measured in units squared; example 24 inches squared or 61 mm squared

* volume is measured in units cubed; example 109 inches cubed or 83 cm cubed

* when calculating area or volume make sure all the input values into your formula have the same units first

* when using pi (3.14) the more digits of pi you use in you calculation the more accurate your answer- don’t round off too much
