A) \[261\,\,c{{m}^{2}}\]
B) \[263\,\,c{{m}^{2}}\]
C) \[213\,\,c{{m}^{2}}\]
D) \[216\,\,c{{m}^{2}}\]
E) None of these
Correct Answer: D
Solution :
If the length of rectangle be x cm then 2 (length + breadth) =60 \[\Rightarrow 2\left( x+\text{ }12 \right)=60\] \[\Rightarrow x+\text{ }12=30\] \[\Rightarrow x+\text{ 18}\] \[\therefore \] Area of rectangle \[=\text{ }Length\text{ }\times Breadth\] \[=18\times 12=216\,\,sq.\,\,cm.\]
