Just need an idea of how to do this.

So, is the method, calculating the areas of the four overlapping semi circles and subtracting that from the area of the square. Then calculating the area of the lightly shaded area by calculating area of circle minus the area of the square?

Thanks.
Resolved! Just figured it out!
