Answer:

  132 units²

Step-by-step explanation:

The figure is a trapezoid, so its area can be found using the formula for the area of a trapezoid.

  A = 1/2(b1 +b2)h

The top "base" is the difference between 21 units and 9 units, so is 12 units. Filling in the numbers, we have ...

  A = 1/2(21 units +12 units)(8 units) = 132 units²

The area of the figure is 132 square units.
