The union of the squares is a poly­ gonal figure enveloping the curve L and the area of the polygonal figure does not exceed the sum of the areas of the constituent squares, i.e. is not greater than -r !)• Since I is fixed and n can be * A rectifiable curve is the one that possesses a finite length.
