A) \[40\text{ }cm,\text{ }50\text{ }cm~\]
B) \[45\text{ }cm\] each
C) \[50\text{ }cm\] each
D) \[45\text{ }cm,\text{ }50\text{ }cm\]
Correct Answer: A
Solution :
Let one side of the parallelogram be 'x' cm. Then adjacent side is \[(x+10)\,cm\]. \[\therefore \]Perimeter \[=x+(x+10)+x+(x+10)=180\] (Given) \[\Rightarrow \] \[4x+20=180\] or \[x=40\,cm\] \[\therefore \] \[x+10=50\,cm\]You need to login to perform this action.
