Why do you insist on asking about more complicated subjects when you do not understand that area is defined as the magnitude of the cross product of the two vectors that compose the sides of the parallelpiped?

Do you want me call your mami? You are, as usual, confused. Whoever taught you vector algebra, assuming it was taught to you, fucked up. Area is not a vector. Open any textbook that has vector analysis within.

Thats not the answer from someone claiming to have a new answer that no one else knows... In other words, you cannot answer. -- For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
