Assume the square has side lengths = 1 so that the area of the square is 1, then the half circles have diameter = 1 (i.e. radius =1/2). Calculate the area of the circle and divide it by the area of the square.

That's fine, all we need is the proportion of the circle compared to the square. So it doesn't matter which length you pick for the side of square. I.e. we can just assume the length of each side of the square = 1.
