If you combine both the shaded areas, they make up one triangle of the eight congruent triangles that make up the entire octagon

Therefore shaded area = (1/8)th of the area of the entire octagon = 12.5 % of the octagon's area

D it is.

Actually there are 8 equilateral triangles in an octagon. From the figure each triangle is divided into 2 parts. So, total triangles is 8x2=16. Area of shaded region is 2/16x100=12.5percnt.
