A) 112.4 sq cm
B) 104.2 sq cm
C) 100.8 sq cm
D) Cannot be determined
Correct Answer: C
Solution :
| [c] Let r be the radius of the circle. \[\therefore \] \[2\,\pi r=132\] \[\Rightarrow \] \[r=\frac{132\times 7}{2\times 22}=21\,cm\] \[\therefore \]Side of the square \[=21\,\,cm\] and length of the rectangle \[=\frac{3}{5}\times 21=12.6\,cm\] Hence, area of rectangle \[=12.6\times 8=100.8\,c{{m}^{2}}\] |
