11 The diagram shows triangle P drawn on a centimetre grid.
(a) Work out the area of triangle P. (1)
Triangle E is an enlargement of triangle P with centre \(O\) and scale factor 2
(b) On the grid, draw triangle E. (2)
(c) On the grid, reflect triangle Q in the line \(x = 1\) (2)

|---|---|
| triangle drawn (−2, 2), (6, 2), (0, −4) | B2 |
| (2) |
Notes
B2: B1 for any translation of the correct enlarged triangle or
an enlargement with the correct centre but wrong SF (for SF≠1)

Notes
M1: For clearly identifying the line \(x = 1\)
or
For a reflection in any vertical line
A1: SCB1 for a correct reflection in \(y = 1\)
