Triangle T has vertices at A(1, 1), B(1, 4) and C(3, 1). Triangle T is translated 4 squares right and 2 squares up to give triangle T'.
Figure (to be drawn): A coordinate grid (0 to 10 on both axes) with triangle T plotted using vertices A(1, 1), B(1, 4) and C(3, 1).
(a)Write the coordinates of the image of vertex B after the translation.(1)
(b)Work out the area of triangle T. You may get a mark for using a correct method even if your answer is incorrect.(2)
