A rectangle has vertices at (2, 1), (2, 5), (7, 5) and (7, 1) on a coordinate grid.
Figure (to be drawn): A coordinate grid with x and y axes numbered from -4 to 8, showing a rectangle plotted with vertices at (2, 1), (2, 5), (7, 5) and (7, 1).
(a)Work out the area of the rectangle.
You may get a mark for using a correct method even if your answer is incorrect.(2)
(b)The rectangle is translated 4 squares left and 3 squares up. Write the new coordinates of the vertex that was originally at (2, 1).(1)
(Total for Question 22 is 3 marks)
