A) \[15\text{ }c{{m}^{2}}\]
B) \[21\,c{{m}^{2}}\]
C) \[16\,c{{m}^{2}}\]
D) \[23\,c{{m}^{2}}\]
Correct Answer: B
Solution :
(b): Area of shaded region = 1/2 (Area of the square ? Area of circle) \[=\frac{1}{2}{{a}^{2}}\left[ 1-\frac{\pi }{4} \right]\] where, a= side of square \[=\frac{{{14}^{2}}}{2}[1-0.785]=98\times 0.215=21\,\,c{{m}^{2}}\]You need to login to perform this action.
