    Answer:

    No, they cannot be added or subtracted.

    Step-by-step explanation:

    According to the homogenity of units and dimensions, the quantities of the same units and dimensions are added or subtracted only.

    So, the quantities of different units and dimensions can not be added or sutracted.

    So,

    cm^2 - cm = notdetremined
