Find the area of a regular octagon with an apothem of 10" and a side length of 3√13 (Remember that the apothem is a line segment drawn from the center that is perpendicular to one side of the polygon) Please explain! :)

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
