The area of square ABCD is 4 times larger than the area of square WXYZ. If the area of square WXYZ is 9, what is the difference between the length of a square ABCD and the length of a side of square WXYZ?
The difference would be 1.5 because the square root of the area of the first square is 2.25, so the sides would be 1.5, and the square root of 9 is 3, so 3-1.5= 1.5
