Rectangle A, 4 cm by 3 cm, and rectangle B, 16 cm by 12 cm

Diagram NOT accurately drawn

Rectangle B is an enlargement of rectangle A.

(a) Write down the scale factor of this enlargement. (1)

Grid with x and y from -6 to 6 showing shape R with vertices (-5, -2), (-2, -2), (-3, -4), (-5, -4)

(b) On the grid above, reflect shape R in the line \(y = -x\) (2)

Grid with x from -2 to 7 and y from -6 to 6 showing triangle P with vertices (2, 2), (2, 5), (4, 2) and triangle Q with vertices (3, -3), (6, -3), (3, -5)
