A:

Hi Dhirendra,

To do so, you should understand the geometrical interpretation of Vector product.

 

Error converting from MathML to accessible text.

Example:

This is the case for a parallelogram.

Using this, we can achieve the formulas for area of a triangle.

We space know space that space the space area space of space the space triangles space formed space by space the space diagonals space of space straight a space parallelogram space equals 1 half area space of space straight a space parallelogram
So comma space area space of space straight a space triangle equals 1 half open vertical bar straight b cross times straight c close vertical bar space
