On the plan, a room in the house has a floor area of 48 cm2
Work out the real area of the floor of this room.
Give your answer in m2 (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 12 | P1 | for process of working with area scale factor, eg area SF \(= 50^2\ (= 2500)\) or \(0.5 \times 0.5\ (= 0.25)\) or \(48 \times 50 \times 50\ (= 120\,000)\) or for process which uses 1 (m2) = 10 000 (cm2), eg \(\dfrac{48}{10\,000}\) |
| P1 | for complete process, eg \(\dfrac{\text{``}120\,000\text{''}}{100 \times 100}\) or \(\text{``}0.25\text{''} \times 48\) | |
