Final answer:
The perimeter of a square is calculated by multiplying the length of one side by 4. If the town square is indeed a square with side lengths of 39.2 meters, the perimeter is 156.8 meters. For a rectangle with different lengths and widths (39.2m by 17.5m), the perimeter would be 113.4 meters.
Step-by-step explanation:
The perimeter of a square is calculated by adding up the lengths of all four sides. Since all sides of a square are equal, the perimeter (P) can be calculated using the formula P = 4s, where 's' is the length of one side. In the context of the question where the statement '48x5' is mentioned but does not pertain to the question, we will ignore it and focus on calculating the perimeter using the provided lengths from the reference information.
Considering the reference information given, we have a town square with a length of 39.2 meters and a width of 17.5 meters. However, this describes a rectangle rather than a square, so the formula for the perimeter of this rectangle would be P = 2l + 2w. If this is indeed a square, with equal side lengths, we should assume that the length and width are the same. If we are to proceed with the information given (treating it as a square), and both the length and width are equal to 39.2 meters, the perimeter can be calculated as P = 4(39.2 meters) = 156.8 meters.
If the intent was to calculate the perimeter of a rectangle instead, using the lengths provided (39.2 meters and 17.5 meters), then the correct formula to apply would be P = 2(39.2) + 2(17.5) = 113.4 meters. If the original question relates to a 'square', the previous calculation applies. If not, and the shape is a rectangle, then the latter calculation is used.
