Question

Write two different expressions given the perimeter of donkeys pen

Answer 1

To express the perimeter of a donkey's pen, we can use two different geometric shapes as examples: a rectangle and a circle.

1. **Rectangular Pen**: If the length of the rectangular pen is \( l \) and the width is \( w \), the perimeter \( P \) can be expressed as:
\[
P = 2l + 2w
\]

2. **Circular Pen**: If the pen is circular with a radius \( r \), the perimeter (which is called the circumference in this case) can be expressed as:
\[
P = 2\pi r
\]

These two expressions illustrate the perimeter of a donkey's pen assuming it has either a rectangular or a circular shape.
