1406
(Accept 1406 or 1406 only. Must be 4 figures.)

2. [2 marks]
1.0 km
(1 mark for correct measurement/calculation logic; 1 mark for correct unit and value. Distance is 2cm on map x 0.5 = 1.0km.)

3. [3 marks]
Description of Relief:

The land is steep / has a steep gradient (1 mark).
This is shown by the contour lines being close together (1 mark).
The height is above 20m/30m (specific value depends on map detail, but referencing elevation gain) (1 mark).
(Must link contour spacing to slope steepness.)

4. [1 mark]
Commercial / High-density Residential / Mixed Use
(Accept any plausible zone adjacent to CBD based on standard urban models.)

5. [2 marks]

Land value/rent is higher near the CBD (1 mark).
Therefore, only high-density (vertical) development is economically viable to maximize profit per square metre (1 mark).
