| Scheme | Marks | Comments |
|---|---|---|
| 1·3 × 0·4 or 130 × 40 | M1 | Must be only the correct method but allow if x/÷ by power of 10 |
| 0·52 or 5200 | A1 | Mark final answer Allow 0·5 provided no incorrect working seen |
| m2 or cm2 | U1 | Correct units for ‘their area’ Eg 1.3 × 0·4 = 0.52 0.52 × 100 = 52 cm2 Award M1 A0 U1 (attempt to change to cm2) |
