    We are asked to solve for the lateral area of the cylinder and the formula is shown below:

    Lateral area = 2*pi*r*h

    We are also given with the area of the base such as:

    Area of the base = 36pi square units

    Area of the base = pi*r²

    Solving for radius:

    36pi = pi*r²

    r=6 inches

    Solving for the lateral area when height is 2 units:

    Lateral area = 2*pi*6*2

    Lateral area = 24pi inches²

    The answer is the letter "B" 24 square units
