    Hints: There is a rotation and scaling involved. Order of transformation is not important (in this case).

    @mathmate : I think it was guide-reflection

    A glide reflection will change the image to the reflected image, which is not the case here. Also, a glide reflection will NOT change the size of the image, here the image and preimage have different sizes! It could be done in one step if matrix is used.

    The question clearly states that you need to describe the composition of transformations to go from FGH to QRS. As I said,"There is a rotation and scaling involved. Order of transformation is not important ", so the composition is \(R\circ S\) or \(S\circ R\) and I will leave it to you to fill in the details of the rotation (CCW 90\(^\circ\)) and scale (1/2).
