Ayuda con con formula DAX

You first need to create a seperate measure for each area : 

Dot_emb_Packing = CALCULATE(
    AVERAGE('Resumen_Bines_por proceso'[dotacion_embalaje_ingreso]),
    'Resumen_Bines_por proceso'[AREA] = "PACKING"
)

Dot_emb_Packing_Carozo = CALCULATE(
    AVERAGE('Resumen_Bines_por proceso'[dotacion_embalaje_ingreso]),
    'Resumen_Bines_por proceso'[AREA] = "PACKING CAROZO"
)

Dot_emb_Hand_Pack = CALCULATE(
    AVERAGE('Resumen_Bines_por proceso'[dotacion_embalaje_ingreso]),
    'Resumen_Bines_por proceso'[AREA] = "PACKING HAND PACK"
)

 Then, you can combine these measures to get the calculation you need. For example, if you want the sum of the dotations from the three areas, you could do something like this:

Dot_Total_Combined = Dot_emb_Packing + Dot_emb_Packing_Carozo + Dot_emb_Hand_Pack
