To find the total area of Oak Manor, which is rectangular in shape, 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
Now, calculate the area:
\[ \text{Area} = 4.2 , \text{miles} \times 3.8 , \text{miles} \]
\[ \text{Area} = 15.96 , \text{mi}^2 \]
Therefore, the total area of Oak Manor is 15.96 mi².
