Ummm....WHAT "shaded region"??

Apparently there's a diagram that accompanies your question which you aren't sharing with us...

mathstudent55 · Answer

The side of the hexagon is the base of the upper triangle.
The apothem is the height of the triangle.
The area of the triangle is (1/2)bh = (1/2)sa
Since it's a hexagon, you have 6 triangles, so the area is 6 *(1/2)sa = 3sa
For an octagon, the area is 4sa (s = side, a = apothem)

mathstudent55 · Answer

In your case, the area of the entire octagon is 4(18.11 * 15.15)
How much of it is shaded?

anonymous · Answer

that is what needs to be found out
