Vector Algebra

Solution:

If we have two vectors $a$ and $b$ represented by the two adjacent sides of a parallelogram in magnitude and direction then their sum $a+b$ is represented in magnitude and direction by the diagonal of the parallelogram through their common point. This is known as the parallelogram law of vector addition.
