An areal feature is something that refers to an area or space. Imagine you have a big piece of paper and you draw a house on it with a black marker. The house has walls, a roof, and a door. These are all features of the house, but they are not areal features. However, if you decide to color the roof in with blue, making it a blue roof, this would be considered an areal feature. It is an areal feature because it is something that only makes sense in relation to a specific area, rather than being a feature that could be applied to the house as a whole. Other examples of areal features include things like geographic boundaries, like the border between two countries, or even man-made objects like the lines painted on roads. Basically, an areal feature is anything that has to do with a specific area, rather than being a feature that could exist on its own or be applied to something else outside that area.
