people per square kilometer? Explain how you know.

Answer 1

Portugal

Explanation:

Brazil

• Area = 8.51 × 10^6 km²
• Population = 1.99 × 10^8 people

Density of population:

• 1.99 × 10^8 / 8.51 × 10^6 =
• 1.99 × 10^2/8.51 =
• 199/8.51 =
• ≈23.38 people/km²

Portugal

• Area = 9.21 × 10^4 km²
• Population = 1.08 × 10^7 people

Density of population:

• 1.08 × 10^7 / 9.21 × 10^4 =
• 1.08 × 10^3 / 9.21 =
• 1080 / 9.21 =
• ≈ 117.26 people/km²

Portugal has a greater number of people per square kilometer
