Let's name the sides of the donkey's pen as "length" and "width".
Expression 1: 2(length + width)
This expression calculates the perimeter by adding the length and width together, then multiplying the sum by 2.
Expression 2: length + length + width + width
This expression calculates the perimeter by adding each side of the pen individually. It adds two lengths (both sides of length) and two widths (both sides of width) together.
Write two different expressions giving the perimeter of the donkey’s pen
