Kenneth Cole kennethcole@home.com last updated: 10 November 2000 How Algebra Tiles Work Algebra tiles work by the concept that every rectangle has a length, width and area. The length and the width are the lengths of the sides of the rectangle in some unit. The area is how many squares of that unit it takes to cover the rectangle. Let's Look at some examples: 5 .
