Read the diagram given below carefully and answer the questions that follow Area of shaded regions
A) \[641\,c{{m}^{2}}\]
B) \[164\,c{{m}^{2}}\]
C) \[224\,c{{m}^{2}}\]
D) \[160\,c{{m}^{2}}\]
Correct Answer:
B
Solution :
= Area of D ABF + Area of BCDG \[=\left( \frac{1}{2}\times 14\times 1 \right)+(Area\,of\,BCDE-Area\,of\,DGED)\] \[=84+\left( 12\times 10-\frac{1}{2}\times 10\times 8 \right)\] \[=84+(120-40)=84+80=164\,c{{m}^{2}}\].
