    Second option: The area increases by 6 square units.

    Step-by-step explanation:

    A1 = ½ * 4 * 3 = 6 units²

    A2 = ½ * 4 * 2 (3) = 12 units²

    Increase: 12 - 6 = 6 units²

    The area increases by 6 square units.

    Step-by-step explanation:

    The original area of triangle

    A = 1/2 bh

    a = 1/2 (4) * 3

    6 square units

    Now we double the height

    A = 1/2 (4) * 6

    A = 12 square units

    The difference is 12-6 = 6 square units
