No, a line is not a polygon. A polygon is a closed plane area bounded by straight sides. A line, by itself, does not contain an area.
the circle is inscribed in the polygon :]
Five sided polygon is pentagon
A 5 sided polygon is a pentagon
84 sq. units
Unless the area is a regular polygon (or a circle) you cannot.
circumscribed means the polygon is drawn around a circle, and inscribed means the polygon is drawn inside the circle. See related links below for polygon circumscribed about a circle and polygon inscribed in a circle.
You haven't given enough information. What kind of polygon is it?
The answer is given below.
More information is required in order to answer this question. What is the shape for which the perimeter is given? If it anything other than a circle or regular polygon it is not possible to determine the area. For a circle or regular polygon, the answer will depend on the shape.
Area of regular polygon: 0.5*20*3 = 30 square feet
The answer will depend on the number of sides in the polygon. Since that information is not given, there can be no answer.
area of a polygon is the amount of area inside the polygon. A square is a polygon and its area is the side length squared, ie times itself. Some polygons are harder to find the area of.
a polygon doesn't have a radius... a circle has a radius. the area of a circle is pi times the radius squared. * * * * * While it is true that a polygon does not have a radius, it does have a circumradius. This is the radius of the circle which passes through each of the polygon's vertices. If the circumradius is r units, and the polygon has n sides, then its area will be 1/2*n*r2*sin(2π/n) square units, where the angle is measured in radians.
Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.
Then the point is not outside the polygon...?
