The expression 8w - 18 can be factored as (4w - 9)(2).
The dimensions of the rectangle are 4w - 9 units and 2 units. The area of the rectangle is the product of these dimensions, which is 8w - 18 square units.
Therefore, we can conclude that the rectangle has a length of 4w - 9 units and a width of 2 units, and the product of these dimensions is equal to 8w - 18 square units.
