The term "m2" refers to square meters, a unit of area measurement in the metric system. It is commonly used to quantify the size of a space, such as a room, a plot of land, or any surface area. One square meter is equivalent to a square that is one meter long on each side. In real estate, understanding m2 is essential for evaluating property sizes and comparing different listings. For example, a house with a total area of 100 m2 may be more or less desirable depending on its location and layout, impacting its value in the market.
