A standard football pitch is quite large so it's common for schools to subdivide it to save on space or make it bearable for younger students.

These fields seem to be usable as two small fields with the yellow lines or one normal sized one with the white lines.

There's no standard size for a soccer field...

So it's not unheard of for complexes to have multiple set ups like this.

Like how a HS gymnasium can have one major basketball court for games, but has like 6 more baskets that can be lowered for practice
