The area of a rectangle is the product of its base and its height. We can also express the area of a rectangle as the product of its length and its width. An area is always given in units of length^2 (“length squared”). In other words, if the dimensions of the rectangle are given in inches, the units for area will be in^2.

Finding the area of a composite of rectangles using sums and differences

In this lesson we’ll look at composite figures made from rectangles and how to find their areas. A composite figure is made by combining different shapes. We’ll find the area of a composite figure by dividing the composite shape into shapes whose areas we already know how to find.
