A) 280 m
B) 325 m
C) 360 m
D) 380 m
Correct Answer: C
Solution :
[c] Let length of rectangle = 5x Breadth of rectangle = 4x \[\therefore \] \[5x-4x=20\] x = 20 \[\therefore \] Length\[=5\times 20=100\,m\] Breadth\[=4\times 20=80\,m\] Perimeter\[=2(l+b)\] \[=2(100+80)=2\times 180\] = 360 mYou need to login to perform this action.
