A) \[6(x-3)\,cm\]
B) \[6(x-6)\,cm\]
C) \[3(x+6)\,cm\]
D) \[(6x+36)\,cm\]
Correct Answer: D
Solution :
Length \[=2(x+6)\,cm\] Width \[=\frac{1}{2}\times \] length \[=\frac{1}{2}\times 2\,(x+6)\,cm=(x+6)\,cm\] \[\therefore \] Perimeter \[=2\,(l+b)\] \[=2[2\,\,(x+6)+(x+6)]\,cm\] \[=6x+36\,cm\]You need to login to perform this action.
