Around the outside of a 4 by 4 square, construct four semicircles (as shown in the figure) with the four sides of the square as
their diameters. Another square, ABCD, has its sides parallel
to the corresponding sides of the original square, and each side
of ABCD is tangent to one of the semicircles. What is the area
of the square ABCD?
