S5 Geography Urban Land Use, Paper 1: bid rent and density
Paper 1 uses bid rent to explain where the CBD, housing and farming sit, then calculates density, housing share, commuting distance, greening ratio and plot ratio.
Focus Commerce bids highest, density is population over area, plot ratio times site gives floor area, and sprawl lengthens commuting and consumes farmland.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | The highest rents and accessibility, dense high rise buildings and mainly commercial and financial uses | The centre is the most accessible point, so the highest bidders take it and land values push buildings upward. |
| 2 | Commercial above residential above agricultural | Commerce earns most per square metre and can pay central rents, while farming needs space and stays at the fringe. |
| 3 | 30 000 people per square kilometre | Density is population divided by area, and 45 000 divided by 1.5 is 30 000. |
| 4 | Low density outward growth into the countryside, with longer commuting and lost farmland | People move to low density housing at the edge, so the centre spreads outward and commuting and infrastructure costs rise. |
| 5 | 30 per cent | Ninety over 300 times 100 is 30, with the rest in roads, industry and green space. |
| 6 | 6000 km | A return trip is 24 km, and times 250 working days gives 6000 km. |
| 7 | 10 per cent | Four point five over 45 times 100 is 10, so nine tenths is built up. |
| 8 | 25 per cent denser, 30 000 against 24 000 per square kilometre | Area A gives 30 000 and area B 24 000, so the gap of 6000 over 24 000 is 0.25. |
| 9 | 200 flats | Two thousand times 5 gives 10 000 square metres of floor area, and divided by 50 that is 200 flats. |
| 10 | Bid rent decides it, through accessibility and land rent, with size only one factor | A commercial user outbids a farmer for the same plot, which is why the centre turns commercial rather than because of size. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
