A) \[\left( 100-25\pi \right)\text{ }c{{m}^{2}}\]
B) \[\left( 100-50\pi \right)c{{m}^{2}}\]
C) \[\left( 50\pi -100 \right)c{{m}^{2}}\]
D) \[\left( 25\pi -100 \right)\text{ }c{{m}^{2}}\]
Correct Answer: C
Solution :
(c): Area of shaded region = 2[Area of quadrant - area (\[\Delta le\,\,ABD\])]. This area can be standardized as, Required area \[=\frac{{{a}^{2}}}{2}(\pi -2)\] where ?a? is length of side of square.
