Point B,DB,D and JJ are midpoints of the sides of right triangle ACGACG . Points K,E,IK,E,I are midpoints of the sides of triangle JDGJDG, etc. If the dividing and shading process is done 100 times (the first three are shown) and AC=CG=6AC=CG=6, then the total area of the shaded triangles is nearest
