Find the area of a star colored in red inscribed in a unit square according to the picture below. E is the midpoint of AB, and other edges follow the same pattern.
+128474 I'm guessing that you wnat to know the ratio of the red area to the area of the square ???
If so
One white area has a base = the side of the square = S
And the height of one of these right triangles = S/4
So....its area = (1/2) S ( S/4) = S^2 / 8
And the toal white area = (4) S^2/8 = S^2/2
So....red area to square area = 1/2
