To calculate the perimeter of the donkey's pen, we need to know the dimensions of the pen. Since you mentioned part b of the question, I assume there are specific dimensions provided there.
Typically, for a rectangular pen, the perimeter (P) can be calculated with the formula:
\[ P = 2 \times (length + width) \]
If you have the length and width from part b, just plug those values into the formula to get the perimeter. Since I don’t have the values from part b, I cannot calculate the perimeter directly.
However, based on the responses you provided, the options given are:
- 72 meters
- 49 meters
- 48 meters
- 36 meters
If you can provide the dimensions of the pen, I can help you calculate the perimeter and pinpoint which of those options is correct!
