If a→=2i^-3j^+k^, b→=-i^+k^, c→=2j^-k^ are three vectors, find t – InterviewSolution

1.	If a→=2i^-3j^+k^, b→=-i^+k^, c→=2j^-k^ are three vectors, find the area of the parallelogram having diagonals a→+b→ and b→+c→. [CBSE 2014]
Answer» If $\vec{a} = 2 \hat{i} - 3 \hat{j} + \hat{k}, \vec{b} = - \hat{i} + \hat{k}, \vec{c} = 2 \hat{j} - \hat{k}$ are three vectors, find the area of the parallelogram having diagonals $(\vec{a} + \vec{b})$ and $(\vec{b} + \vec{c})$ . [CBSE 2014]
