Final answer:
To calculate the perimeter of a rectangle, one uses the formula P = 2l + 2w. For a town square with a length of 39.2 meters and a width of 17.5 meters, the perimeter is 113.4 meters. Additional information is needed for other shapes.
Step-by-step explanation:
To find the perimeter of a four-sided shape, one must add the lengths of all four sides together. If the shape is a rectangle, and we know the length and width, we can use the formula P = 2l + 2w to calculate the perimeter, where l represents the length and w represents the width of the rectangle.
Given the town square's length of 39.2 meters and a width of 17.5 meters, we can apply this formula:
- The perimeter P = 2 * 39.2 + 2 * 17.5
- P = 78.4 + 35.0
- P = 113.4 meters
If the student asked about a different shape ABCD without providing specific measurements, an accurate answer cannot be provided without additional information.
