A straight line joins the midpoints of 2 opposite edges of a square of edge 'a' units, dividing it into 2 rectangles. In one of the rectangles, mid-point of a larger side is joined to the opp vertices to form a triangle. Now the mid-points of the 3 sides of the triangle constitute another triangle and so on. In the other rect, the mid-points of 4 sides are joined to form a rhombus. In this rhombus the mid-points of the 4 sides are joined again to form a rect and so on. Find the total area of all the figures (viz. square, triangles, rectangles and the rhombus constructed) so formed.
