A) 26 cm
B) 52 cm
C) 104 cm
D) 13 cm
Correct Answer: B
Solution :
(b): Let the common ratio be = x Then, length = 4x, breadth = 3x and height = 2x As per question: \[2(4x.3x+3x.2x+2x.4x)=8788\] \[\therefore \] \[2(12{{x}^{2}}+6{{x}^{2}}+8{{x}^{2}})=8788\] \[\Rightarrow \] \[52{{x}^{2}}=8788\Rightarrow x=13\] \[\therefore \] Length \[=4x=52\text{ }cm\].You need to login to perform this action.
