Learn how to find the area of a rectangle. This lesson explains the formula for determining the area of a rectangle and includes examples of its use.

When given a rectangle's perimeter, as well as a relationship between the two sides, we can write two unique equations relating the length and width of the rectangle.

A rectangle’s sides are usually called its length and width. However, these may sometimes instead be referred to as the height and base. The latter terms are used more commonly for triangles. To find …
