If the vericies of square A are the midpoints of the efge if square B then waht is the ration of the are of square A to square B?
Sorry I don't have time to do the problem out right now, but you should draw a picture and use the triangles in the corners of the big square. The length of the sides of those triangles. And try to edit your posts for spelling errors next time, it's very hard to understand the question.
