How is the area of a rectangle determined?
The area of a rectangle or some other polygon is a number of square units needed to fill the rectangle. The area, usually denoted by A A, of a rectangle with the length of a a and the width of b b is A = length × width = a × b A = length × width = a × b In other words, the area of a rectangle is the product of its length and width.
