(a) A diagonal of a rectangle is drawn on a centimetre grid.
The sides of the rectangle are on the grid lines.
Work out the area of the rectangle. [2 marks]
(b) One side of a parallelogram is drawn on this centimetre grid.
The parallelogram does not have any right angles.
Complete the parallelogram so that it has area 24 cm\(^2\) [2 marks]
(c) Two sides of a rhombus are drawn on this grid.
Complete the rhombus. [1 mark]

|---|---|---|
| 3 or 4 identified or 4 by 3 rectangle drawn on grid or triangle base 4, height 3 drawn on grid | M1 | |
| 12 | A1 |
Additional guidance
| \(\dfrac{3 \times 4}{2}\) | M1A0 |
| \(3 + 4 + 5 = 12\) (perimeter of triangle, not area of rectangle) | M1A0 |
| For drawings, mark intention | |
| Ignore units |

|---|---|---|
| All three of • parallelogram with side as given • no right angles • area 24 cm\(^2\) | B2 | B1 any two bullet points |
Additional guidance
 | B2 |
| Vertices along the bottom edge do not need to be at intersections of gridlines | |
| Mark intention for B2 and B1 | |
| Rectangle with sides 6 cm and 4 cm | B1 |
| Non right-angled triangle drawn off given line, with vertical height 8 cm | B1 |
| Trapezium (no right angles) drawn with parallel lines of length 6 cm and 10 cm, vertical height 3 cm | B1 |
| For those that start again, a horizontal line of 6 cm must be used |

|---|---|---|
| Rhombus drawn using given two sides | B1 |
Additional guidance
 | B1 |
| Mark intention of straight lines | |
| Ignore diagonals on a correct rhombus |
