To find the total area of the town of Oak Manor, you can use the formula for the area of a rectangle:
\[ \text{Area} = \text{length} \times \text{width} \]
Given:
- Length = 4.2 miles
- Width = 3.8 miles
Calculating the area:
\[ \text{Area} = 4.2 , \text{miles} \times 3.8 , \text{miles} = 15.96 , \text{mi}^2 \]
So, the total area of Oak Manor is 15.96 mi² (15.96 square miles).
The correct response is:
15.96 mi² (or 15.96 mi squared).
