Dear Aalu Jasto:

Your answer is NOT CORRECT.

Please, be careful as value of Pi is '22 divided by 7' which is equal to approx 3.14.

Therefore, area of the square is 4inchesx4inches =16 sq inches.

Area of circle is 3.14x2inchesx2inches). However, WE WANT ONLY only ONE-FOURTH. Therefore, 1/4=3.14.

WE ARE INTERESTED IN the MIDDLE AREA, by subtracting the enclosed area of 1/4th circles.
which will be: 16-3.14 or approximately 12.86.

PLEASE NOTE: It will be wrong if you say "16 minus 3.4336".

Be careful guys & gals.
