What if pupils find this a barrier?
Use an acetate grid marked in cm² to help 'count squares' and develop concept of area.
Work with irregular shapes as well as shapes that can be divided easily into rectangles.
The focus is on having a feeling for area, not calculating the area.
Deal with the misconception that area is length × width regardless of the shape!
