Question

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?

Answer 1

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
