Imagine a square ABCD with a diagonal BD. Now draw a line EF parallel to BD, such that E lies on BC and F lies on CD. Also length of EF = length of AB. Now Colour the space enclosed by BDFE.
Of the square ABCD, what percentage of area is coloured ?
To Sean and Fletch, yes, the problem is easy. That's why up in the corner (far right of the problem's title) the difficulty rating is a 1 out of 5.
