You add together the lengths of the nine sides of the nonagon.
The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
The area is 1583 square units, approx.
Each side is 117/9 = 13 cm
The perimeter is zero, since there is no trapezoid below.
It is the sum of the lengths of the nine sides of the nonagon.
