Not drawn accurately
| Answer | Mark | Comments |
|---|---|---|
| \(32^2\) and \(60^2\) or 1024 and 3600 or 4624 | M1 | |
| \(\sqrt{32^2 + 60^2}\) or \(\sqrt{1024 + 3600}\) or \(\sqrt{4624}\) | M1dep | |
| 68 | A1 |
Additional guidance
| Answer only 68 | M1M1A1 |
| \(68 = 2\sqrt{17}\) incorrect further working | M1M1A0 |
| 68 from scale drawing | M0M0A0 |
| 68 from trigonometry | M0M0A0 |
