Using Formulas
A formula is an equation that shows a relationship between 2 or more variables. The formula for the area of a rectangle is `a = l⋅w`. Given the length and width of an object, you can easily find the area. Be careful, however, and make sure that you are using consistent UNITS in the formula. Do not mix up seconds with minutes or hours or inches with feet or miles. The units must ALWAYS be consistent.
