The three numbers that represent an area in a geometrical context could refer to a variety of things depending on the specific area you're discussing. However, if you are referring to the three numbers that define the dimensions of a three-dimensional space, they could be called:
- Length - One dimension of the area.
- Width (or Breadth) - Another dimension.
- Height - The third dimension.
In some contexts, such as in mathematics or certain applications, these could also refer to the coordinates of a point in a three-dimensional space, which could be expressed as (x, y, z).
If you meant something else, please provide more context!
