A) \[\frac{260}{3}\text{m}\]
B) 240 m
C) \[\frac{280}{3}\text{m}\]
D) 360 m
Correct Answer: C
Solution :
Let length be 5x and breadth be 2x. \[\because \] \[5x-2x=20\] \[3x=20\] \[\Rightarrow \] \[x=\frac{20}{3}\] \[\therefore \]Perimete\[=2\,\,(5x+2x)=14x=14\times \frac{20}{3}=\frac{280}{3}\,\,\text{m}\]You need to login to perform this action.
