 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 an 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. 
 
+Geometrically , the determinant of a 2 by 2 matrix is the area of a unit square when the matrix transformation is applied to the plane.

 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.
 
 Given a matrix A, the determinant of A (written as |A|) is given by the following equation:
