What is its area?
A) \[200\,c{{m}^{2}}\]
B) \[186\,c{{m}^{2}}\]
C) \[210\,c{{m}^{2}}\]
D) \[196\,c{{m}^{2}}\]
Correct Answer: C
Solution :
Clearly, the figure is a rectangle. \[\therefore \] \[2\,(x+3)=x+8\] \[\Rightarrow \] \[2x+6=x+8\] \[\Rightarrow \] \[x=2\,cm\] \[\therefore \] Area \[=(x+8)\,\,(6x+9)\] \[=(2+8)\,\,(6\times 2+9)\] \[=10\times 21=210\,\,c{{m}^{2}}\]
