Higher January 2020 Paper 1 Q3
3 The diagram shows a shape.
Diagram NOT accurately drawn
The shape has area 129 cm²
Work out the value of \(x\).
(4)
| Scheme | Marks |
|---|---|
| E.g. 12 × 9 (= 108) or (9 – 6) × \(x\) (= \(3x\)) | M1 |
| E.g. 129 – ‘108’ (= 21) or ‘108’ + ‘\(3x\)’ = 129 | M1 |
E.g. ‘21’ ÷ (9 – 6) or \(x = \dfrac{129 - \text{‘}108\text{’}}{9 - 6}\) | M1 |
| 7 | A1 |
| (4) | |
| (4 marks) |
Notes
M1: for one correct relevant area
M1: (dep on M1) for 129 used correctly with another area
or
for a correct equation (ft) with bracket(s) expanded
M1: for a complete method
A1: Accept 7 cm
