A) \[\sqrt{450}\]
B) \[\sqrt{150}\]
C) \[\sqrt{50}\]
D) \[\sqrt{200}\]
Correct Answer: A
Solution :
\[{{l}_{1}}=\sqrt{25+25}=5\sqrt{2},\] \[{{l}_{2}}=\sqrt{25+25}=5\sqrt{2}\],\[{{l}_{3}}=5\sqrt{2}.\] Hence, \[{{l}_{1}}+{{l}_{2}}+{{l}_{3}}=3\sqrt{50}=\sqrt{450}.\]You need to login to perform this action.
