A) \[100\,c{{m}^{2}}\]
B) \[110\,c{{m}^{2}}\]
C) \[120\,c{{m}^{2}}\]
D) \[125\,c{{m}^{2}}\]
Correct Answer: B
Solution :
Area of shaded portion = Area of rectangle ABCD - {Sum of areas of \[\Delta \,EAF\]and \[\Delta \,EBC\]] \[=\left[ (18\times 10)-\left\{ \frac{1}{2}\times 6\times 10+\frac{1}{2}\times 10\times 8 \right\} \right]\] \[=[180-(30+40)]=(180-70)=110\,c{{m}^{2}}\]
