A) 98 \[c{{m}^{2}}\]
B) 84 \[c{{m}^{2}}\]
C) 108 \[c{{m}^{2}}\]
D) 112 \[c{{m}^{2}}\]
E) 128 \[c{{m}^{2}}\]
Correct Answer: A
Solution :
Area of the circle = \[\pi {{r}^{2}}\] \[\Rightarrow \]\[\pi {{r}^{2}}=154\] \[\Rightarrow \]\[{{r}^{2}}=\frac{154\times 7}{22}=49\] \[\therefore \]\[r=7cm\] Length of the rectangle = Diameter of the circle Breadth of the rectangle = Radius of the circle \[\therefore \] Area of the rectangle\[=14\times 7=98\,c{{m}^{2}}\]
