A vector can be multiplied by another vector but may not be divided by another vector. There are two kinds of products of vectors used broadly in physics and engineering. One kind of multiplication is a scalar multiplication of two vectors. Taking a scalar product of two vectors results in a number a scalar , as its name indicates. Scalar products are used to define work and energy relations.
The first thing to notice is that the dot product of two vectors gives us a number. Certain basic properties follow immediately from the definition. For any vectors a, b.

I follow your graphical derivation in Figure 1b which, by the way, will look quite different when Bx is negative , but I still want to connect it to an intuition behind the remarkably simple formula. I haven't got an answer, but here are two thoughts in this direction Avi asked "Why should the area be related to.. It should give answers on polygons there may exist 'un-measurable' sets, but polygons in particular should be OK , and in particular on parallelograms.
It has many applications in mathematics, physics , engineering , and computer programming.
