Make use of the "area of triangle" (basically area of square/rectangle ÷ 2) for the bottom 2 unshaded triangles
Then use similar triangles for the top unshaded triangle
After that you should be able to find the total unshaded area and form a fraction with the total area
Quite a tricky question :O
Hope this helps :)
