Which way to choose the variables is YOUR choice. Assign them in a way that seems sensible.

The described swimming pool has a dimension of length and a dimension of width. You need to assign a variable to each; one dimension is given as related to the other dimension.

The description begins as {length}=15+{width}.
The perimeter is then given so that you have 2*{length}+2{width}=82.

You would not want to keep writing those words for the dimensions. You want to assign meaningful variables to each. Now, YOU PICK the variables.
