| Scheme | Marks |
|---|---|
| Splits shape appropriately eg rectangle + triangle or rectangle + trapezium or ‘completing the rectangle’ | B1 |
eg. 8 × 11 or 88 or 0.5 × 4 × 6 or 12 or 8 × 7 or 56 or \(\dfrac{4}{2} \times (8 + 14)\) or 44 or 11 × 14 or 154 or \(\dfrac{6}{2} \times (7 + 11)\) or 54 | M1 |
eg. 8 × 11 + 0.5 × 4 × 6 (=88+12) or 8 × 7 + \(\dfrac{4}{2} \times (8 + 14)\) (=56+44) or 11 × 14 or 154 – \(\dfrac{6}{2} \times (7 + 11)\) (=154−54) | M1 |
| 100 | A1 |

Notes
B1: If lines not present on diagram then can be implied by correct method for at least 2 areas (areas must not overlap or be contradictory)
M1: for area of one rectangle, triangle or trapezium from the diagram
M1: for complete method
