A) 48 cm
B) 32 cm
C) 26 cm
D) 52 cm.
Correct Answer: A
Solution :
[a] Sides are in the ratio \[\frac{1}{2}:\frac{1}{3}:\frac{1}{4}\] i.e. \[6:4:3\] Let the ratio be x \[\therefore \] sides are 6x, 4x and 3x Given that 6x + 4x + 3x + = 104 \[\Rightarrow 13x=104\] \[\Rightarrow x=8\] \[\therefore \] Longest side \[=6x=6\times 8=48\,\,cm\]You need to login to perform this action.
