Foundation June 2022 Paper 2 Q16
16 On a scale drawing, a building has length 12.4 cm and width 9.4 cm.
The real length of the building is 62 metres.
Work out, in metres, the real width of the building. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 47 | P1 | for process to find scale factor eg \(62 \div 12.4\ (= 5)\) or \(12.4 \div 62\ (= 0.2)\) or \(9.4 \div 12.4\ (= 0.758...)\) or \(12.4 \div 9.4\ (= 1.31..)\) |
| P1 | for process to use the scale factor eg \(\text{``}5\text{''} \times 9.4\) or \(9.4 \div \text{``}0.2\text{''}\) or \(62 \times \text{``}0.758..\text{''}\) or \(62 \div \text{``}1.31..\text{''}\) | |
| A1 | Accept answers in the range 46.5 to 47.7 |
Additional guidance
Note 1:500 is an acceptable scale factor
Accept working in mixed units or with inconsistent units eg \(620 \div 12.4\ (= 50)\) for process marks only
