Answer:
4milesĀ²
Explanation:
Area of a square = Length * Length
If the neighborhood is in the shape of a square and each street is 2 miles long, then the length of the square is 2 miles.
Area of the neighborhood can simply be calculated using the area for finding the area of a square.
Area of the neighborhood = 2miles * 2miles
Area of the neighborhood = 4milesĀ²
