No it's not, and would that function even work?
Cuz you need to set both minx, miny, maxx and maxy...

pawn Код:

public IsPlayerInArea(playerid, Float:minx, Float:maxx, Float:miny, Float:maxy)
{
    new Float:X, Float:Y, Float:Z;
    GetPlayerPos(playerid, X, Y, Z);
    if(X >= data[0] && X <= data[2] && Y >= data[1] && Y <= data[3]) 
        return 1;
    return 0;
}

Use a timer to check if a player is inside that area
