Answer :

GinnyAnswer
The perimeter \( P \) of a rectangle is calculated using the formula: \[ P = 2 \times (\text{length} + \text{width}) \] Given that the length \( L \) of the rectangle is 12 meters and the width \( W \) is 5 meters, we plug these values into the formula: \[ P = 2 \times (12 + 5) \] \[ P = 2 \times 17 \] \[ P = 34 \text{ m} \] Therefore, the perimeter of the rectangle is 34 meters. The correct answer is: D. 34 m
