Simple the Perimeter you just add the outside numbers. For area. When I look at an octagon I see a rectangle and two Trapezoids on either side of the rectangle. So find the area of each object then add the areas up and voila you got the area of a rectangle.

You cannot. The perimeter alone does not provide enough information unless the octagon is regular and there is no valid reason to assume that it is.

The area of a polygon is not enough to determine its shape - unless it is a regular polygon. There is nothing in the question to suggest that the octagon is regular.

If the sides are of length 4 units then the perimeter is 8*4 = 32 units. Its area is then 77.255 square units.
