Question : If $(a+b+c)=17$, and $\left(a^2+b^2+c^2\right)=115$, find the value of $(a+b)^2+(b+c)^2+(c+a)^2$.
Option 1: 402
Option 2: 408
Option 3: 394
Option 4: 404
Correct Answer: 404
Solution : Given, $(a+b+c)=17$ Squaring both sides $\left(a^2+b^2+c^2\right)+2(ac+bc+ab)=289$ ⇒ $115+2(ab+bc+ac)=289$ ⇒ $2(ab+bc+ac)=174$ Now, $(a+b)^2+(b+c)^2+(c+a)^2$ = $2(a^2+b^2+c^2)+2(ab+bc+ac)$ = $2\times 115+174$ = $230 + 174$ = $404$ Hence, the correct answer is 404.
