Area is measured in square units because it represents the amount of two-dimensional surface a shape covers. It is quantified by counting how many unit squares fit inside the region.
Conditions: Applies to 2-D surface coverage.; The chosen length unit determines the square-unit label.

No, the order of addition does not matter. You get the correct perimeter regardless of the sequence in which you add the side lengths, because they are the same set of numbers being summed.
Conditions: The same set of side lengths is being summed.; Addition is ordinary real-number addition.
