Answer:

  72 square units

Step-by-step explanation:

The figure shown has a uniform horizontal cross section, so is equivalent to a rectangle with length 12 and height 6. Its area is given by the rectangle formula:

  A = LW

  A = (12)(6) = 72 . . . . square units

Additional comment

Essentially, the semicircle removed from the left side is tacked onto the right side. The rectangle area is unchanged by that.
