No, because the degree of failure of the tiling is judged against the area of the covering shape.

This is one of the more confusing problem statements, but I think I understand. So if we choose a regular hexagon with height = 0.5, as in this link, the scoring for this solution would be ((area of triangle - area of hexagon) + (area of square - 3 * area of hexagon)) / area of hexagon?
