Answer:
We cannot determine the length of the park with only the information provided.
Explanation:
If we assume that the park is a rectangular shape, then we can use the formula for the perimeter of a rectangle, which is P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
If the perimeter of the park is 48 miles, then we can set up the equation as:48 = 2(l + w)
If we know one of the dimensions (either the length or the width), then we can solve for the other dimension. However, the problem does not give us any information about the width or the dimensions of the park, so we cannot determine the length of the park with only the information provided.
