带水平填充符的方形 ▤

This symbol is used in geographic maps, education, IQ assessment tests, and textual graphics.

First of all, such a square can be often seen in map legends, where it represents various features of the location, its relief and landscape. But it's not the only option. In basic drawing it is used to indicate a flat composition where all elements are on the same level.

Secondly, a square with horizontal lines is commonly used in IQ tests. There are 5 lines, but in one row horizontally, vertically, or diagonally, squares with fewer or more lines can be present.

Lastly, a square with horizontal fill is used in textual graphics on website pages and social media platforms.
