Linear transformations of the figures are commonly used in computer graphics. There are 2 main types of linear transformations:

1. Rotation transformation rotates a figure around a specific point or axis.
2. Scale transformation resizes a figure by changing its size along each axis.

Your task is to apply all these transformations to a rectangle one by one. As a result, we will have a composition of transformations:

1. Сreate rotation matrix that rotates a figure by np.pi / 3 degrees.
2. Create a scaling matrix with the parameters scale_x = 2 and scale_y = 0.5.
3. Apply the rotation_matrix to the square.
4. Apply the scaling_matrix to the result of the previous transformation.
