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 :)
