## 2 by 2 Determinants
In linear algebra, the determinant of a two-by-two matrix is a useful quantity.Mostly it is used to calculate the area of the given quadilateral(convex polygons only) and is also a easy representation of a quadilateral(convex polygons only) to be stored in computers as arrays. Scientists, engineers, and mathematicians use determinants in many everyday applications including image and graphic processing.

Calculating the determinant of a square two-by-two matrix is simple, and is the basis of the [Laplace formula](https://en.wikipedia.org/wiki/Laplace_expansion) used for calculating determinants for larger square matrices.
