To solve for the total area of Oak Manor, we need to multiply the length and width of the town.
Area = length * width
Area = 3.8 miles * 4.2 miles
Area = 15.96 square miles
Therefore, the correct response is: 15.96 mi2 or 15.96 mi squared.

The correct answer is "the portion of the how-to books that are about either carpentry or electronics."
In the equation, 0.3 represents the proportion of books in the school library that are how-to books, and 0.4 represents the proportion of how-to books that deal with electronics. When you multiply these two numbers together (0.3 × 0.4), you get 0.12. This means that 0.12 or 12% of the how-to books in the library deal with either carpentry or electronics.
