The video tutorial explains how to graph coordinates in R2 and define a rectangle using position vectors. It covers calculating the area of the rectangle and then applies a transformation to the rectangle using a matrix. The tutorial demonstrates how to determine the area of the transformed rectangle by using the determinant of the transformation matrix, illustrating the concept with examples and visual aids.

• 0, k2

• 0, 0

• k1, 0

• k1, k2
