**rebecca**, Saturday, May 4, 2013 at 8:47pmthe 10 is on one of the lines of the polygon then a line from the center

**Damon**, Saturday, May 4, 2013 at 9:00pmIf your radius is to the corners, then

10 = 2* 13.07 sin (180/n)

sin (180/n) = .382555

180/n = 22.5

n = 8 sides

360/8 = 45 = top angle of each isoceles triangle

half of that has hpotenuse of 13.07 and base of 5

area of each of those 16 triangles = (1/2) (5)(13.07 cos 22.5) = 30.2

16*30.2 = 483

**Damon**, Saturday, May 4, 2013 at 9:08pmIf your radius is to the center of each side then

tan (360/2n) = 5/13.07

180/n = 20.93

n = 8.59 sides

I doubt if that is what it means so use my previous answer.
