Show that area of the prallelogram whose diagonals are given by →a a – InterviewSolution

1.	Show that area of the prallelogram whose diagonals are given by →a and →b is →a×→b2. Also, find the area of the parallelogram, whose diagonals are 2^i−^j+k and ^i+3^j−^k.
Answer» Show that area of the prallelogram whose diagonals are given by $\to a a n d \to b i s \frac{\to a \times \to b}{2}$ . Also, find the area of the parallelogram, whose diagonals are $2^i -^j + k a n d^i + 3^j -^k .$
