Work out area of Shape A : area of Shape B
Give your answer in its simplest form. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| 20 or 12 or 10 : 6 | B1 | oe ratio check diagram for area counting to 20 or 12 |
| 5 : 3 | B1ft | ft if B0 awarded, a correct and full simplification of any unsimplified ratio condone \(\dfrac{5}{3} : 1\) or \(1.\dot{6} : 1\) or \(1 : \dfrac{3}{5}\) or 1 : 0.6 SC1 3 : 5 |
Additional guidance
| 5 : 3 with no working | B2 |
| Ignore any units given with the answer | |
| 18 : 16 = 9 : 8 (perimeter) | B0B1ft |
| Poor unit notation can score a maximum of B1 unless recovered \(20^2\) or \(12^2\) or \(5^2 : 3^2\) | B1B0 |
