WebThe area of the little box starts as 1 1. If a matrix stretches things out, then its determinant is greater than 1 1. If a matrix doesn't stretch things out or squeeze them in, then its determinant is exactly 1 1. An example of this is a rotation. If a matrix squeezes things in, then its determinant is less than 1 1.
