What is the perimeter of a rectangle with a length of 12 meters and a width of 5 meters?

To find the perimeter of a rectangle, you use the formula:

Perimeter = 2 * (length + width).

In this case, the length is 12 meters and the width is 5 meters. First, you add the length and the width together:

12 meters + 5 meters = 17 meters.

Next, you multiply this sum by 2 to calculate the perimeter:

2 * 17 meters = 34 meters.

Therefore, the correct calculation leads to a perimeter of 34 meters, confirming that this is indeed the right answer. The other options do not align with the mathematical process used to calculate the perimeter of a rectangle based on the given length and width.
