The length \(AB\) is five times the length \(BC\).
\(AC = 90\) cm.
Work out the length \(AB\). (3)
| Answer | Mark | Notes |
|---|---|---|
| 75 | P1 | for \(90 \div 6\ (= 15)\) or for connecting \(AB\) and \(BC\) by ratio or proportion eg 5 and 1 on the diagram |
| P1 | for a complete method to find the length \(AB\) eg \(90 \div 6 \times 5\ (= 75)\) | |
| A1 | cao |
