Final answer:
The perimeter of the rectangle on the coordinate plane is 113.4 meters to the nearest tenth of a unit, using the formula P=2l+2w.
Step-by-step explanation:
The perimeter of the town square which is a rectangle can be found using the formula P=2l+2w, where P stands for perimeter, l for length, and w for width. Given that the length (l) of the town square is 39.2 meters and the width (w) is 17.5 meters, we can calculate the perimeter to be 2 * 39.2 + 2 * 17.5 meters. Performing the calculation, the perimeter is 113.4 meters, which means the correct answer is Option 4: 113.4 units, rounded to 113.4 meters for the nearest tenth of a unit.
To find the perimeter of a rectangle, we add up the lengths of all its sides. In this case, the rectangle has a length of 39.2 meters and a width of 17.5 meters. The formula for finding the perimeter of a rectangle is P = 2l + 2w, where l is the length and w is the width. Plugging in the values, we get P = 2(39.2) + 2(17.5) = 78.4 + 35 = 113.4 meters. Rounding to the nearest tenth, the perimeter of the rectangle is approximately 113.4 meters.
