The table below shows the population and area of each island in June 2023.
| Population | Area (km\(^2\)) | |
|---|---|---|
| South island | \(1.2 \times 10^6\) | \(1.5 \times 10^5\) |
| North island | \(4.0 \times 10^6\) | \(1.1 \times 10^5\) |
Work out the overall population density of the country in June 2023. [4]

| 20 or \(2 \times 10^1\) or \(2 \times 10\) nfww | 4 | M1 for \(1.2 \times 10^6 + 4[.0] \times 10^6\) or \(5.2 \times 10^6\) oe M1 for \(1.5 \times 10^5 + 1.1 \times 10^5\) or \(2.6 \times 10^5\) oe M1 for \(\dfrac{\textit{a population value}}{\textit{an area value}}\) | may be implied by figs 52 may be implied by figs 26 Award M marks even if not used to find final answer as long as it is not contradicted. Population and area values must be consistent eg both south island, both north island or their summed population and area e.g. M1 implied by 8 or 36.36 to 36.4 or 44.36 or 44.4 |
