A) 50 m
B) 60 m
C) 96 m
D) 66 m
Correct Answer: B
Solution :
(b): 3x = 2y; Perimeter = 132 m \[\Rightarrow 2\left\{ 3x+(x+y) \right\}=132\Rightarrow 4x+y=66\] \[\Rightarrow 4x+\frac{3x}{2}=66\Rightarrow 11x=132\] \[\Rightarrow x=12\Rightarrow y=18\] Perimeter of one rectangle \[=2(x+y)=2(12+18)=60\]You need to login to perform this action.
