A transformation represented by the matrix

      

A transformation represented by the matrix q232082019946.png maps the points A(0, 0), B(2, 0), C(2, 3) and D(0, 3) of the quad ABCD onto A¹B¹C¹D¹ respectively.

(a) Draw the quadrilateral ABCD and its image A¹B¹C¹D¹.

(b) Hence or otherwise determine the area of A¹B¹C¹D¹.

(c) Another transformation q23a2082019946.png maps A¹B¹C¹D¹ onto A¹¹B¹¹C¹¹D¹¹. Draw the image A¹¹B¹¹C¹¹D¹¹.

(d) Determine the single matrix which maps A¹¹B¹¹C¹¹D¹¹ back to ABCD.
