Transcript text: What are the correct units for the area of the region? There may be more than one correct answer. i. $\mathrm{mi}^{3}$ ii. Square miles iii. Miles iv. $m i^{2}$

Solution

Solution Steps

To determine the correct units for the area of a region, we need to identify units that represent two-dimensional space. Area is typically measured in square units.

Step 1: Identify Units for Area

To determine the correct units for the area of a region, we need to identify units that represent two-dimensional space. Area is typically measured in square units.

Step 2: Evaluate Each Option

Option i: $\mathrm{mi}^{3}$ represents cubic miles, which is a unit of volume, not area.
Option ii: "Square miles" explicitly indicates a two-dimensional measurement, which is appropriate for area.
Option iii: "Miles" is a linear measurement, not suitable for area.
Option iv: $mi^{2}$ is another way to denote square miles, which is appropriate for area.
