Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.

Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.

Georgia [21]

To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.

Area = (8+12)/2 = 20/2 = 10

10 x 9 = 90 square centimeters.
