Question 1180552
<br>
Draw a sketch of the circles aligned on the diagonal of the square.<br>
Consider points A and B, which are the centers of the two circles in the corners of the square.<br>
Each of those points is 1 unit from each side of the square; and the length of AB is 8 units.  AB is the hypotenuse of an isosceles right triangle.  Use those pieces of information to find the length of the side of the square.<br>
Then the answer to the problem is the area of the square, minus the area of the 5 circles with radius 1.<br>
