For an Idaho case study of interpreting land-area and total-area measurements, which statement is best supported?

• All square-mile measures include exactly the same features.
• Rocky landscapes are always more densely settled than cities.
• Physical terrain and the way it is measured affect settlement, travel, and comparisons.
• Elevation has no effect on transportation costs.
