A) 2017 cm
B) 4022 cm
C) 6051 cm
D) 7051 cm
Correct Answer: C
Solution :
\[A{{A}_{1}}{{A}_{2}}{{A}_{3}}{{A}_{4}}{{A}_{5}}{{A}_{6}}{{A}_{7}}{{A}_{8}}{{A}_{9}}{{A}_{10}}{{A}_{11}}{{A}_{12}}B=\] \[x+x+x+y+y+y+z+z+z+\]\[a+a+a+b+b=b+c+c+c\] \[=3x+3y+3z+3a+3b+3c\]\[=3(a+b+c+x+y+z)\] ? (i) \[AB=2017\,\,cm=x+y+z+a+b+c\] ? (ii) Putting (ii) in (i) \[\Leftrightarrow \]\[3\times 2017\,\,cm=6051\,\,cm\]You need to login to perform this action.
