A rectangle that is two tiles wide can have an infinite number of tiles. In order to determine the number of tiles in a rectangle, the length of the rectangle in terms of tiles must also be considered.
A rectangle is a shape in which the length and the width are not necessarily the same. While the width of a rectangle is two tiles, the length could be anything from one to an infinite number of tiles while still remaining a rectangle. To determine the total number of tiles, or the area of the rectangle, multiply the width by the length. For example, if the width is two tiles and the length is three tiles, then the total number of tiles is six.
