Given: Two adjacent sides of triangle, A = 3i - 4j + 2k, B = i + j - 2k
To find: Area of triangle
Formula: Area of triangle = \(\frac{1}{2}\) × |cross product of two adjacent sides|
Calculation: Cross product of \(\overset\rightarrow{A}\) and \(\overset\rightarrow{B}\) is given by, \(\overset\rightarrow{A}\times\overset\rightarrow{B}\)
From formula,
Area of the triangle is 6.1 m2.
