Question 959765
Take the area of the large (28" x 28") square, subtract the area of the 14" radius circle
and add back the area of the inner square (1/2  the area of 4 - 14" x 14" squares):
Shaded Area=large square area-circle area+small square area
Shaded area={{{(28in)^2-(pi)(14in)^2+(4)(1/2)(14in)^2}}}
Shaded area={{{784in^2-(22/7)196in^2+392in^2}}}
Shaded area={{{784in^2-616in^2+392in^2=560in^2}}}
ANSWER: The shaded area is 560 square inches.
