a paving stone is in the shape of a regular octagon. the distance from the center to one of the vertices is 15cm. Determine the area of one paving stone to the nearest hundredth of the square centimeter.

length of side = 2*5*sin(22.5)

  = 11.48

length of perpendicular = 5*cos(22.5)

 = 13.86

area = 8 * 13.86 * 11.48

 = 1273 square cm
