Final answer:
The outer perimeter of the town square with the given dimensions is 113.4 meters when rounded to the nearest hundredth.
Step-by-step explanation:
To find the outer perimeter of the town square with a length of 39.2 meters and a width of 17.5 meters, we use the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the width. Plugging in the given measurements, we get P = 2 * 39.2 meters + 2 * 17.5 meters. This calculates to P = 78.4 meters + 35 meters, which equals a total perimeter of 113.4 meters. When rounding to the nearest hundredth, we'll just keep it as 113.4 meters as it is already at the hundredth place.
