The Fencing Problem

Extracts from this document...


The Fencing Problem I am writing this investigation for a farmer who has 1000m2 of fencing and wants to find out how he can create the most area by using the fencing and rearranging the fence in different shapes. From only 3 sides to 99999 sides I have worked out the highest and lowest area for the farmers plot of land. ...read more.


(500-500) (500-300) =5916.079 Area = 500(500-400) (500-400) (500-200) =38729.833 Area = 500(500-450) (500-450) (500-150) =20916.501 Now I will try a different family of shapes a 4 sided shape but I think that the greatest area of a shape will come from a regular shape. Area = 250 x 250 = 62,500m2 Area = 200 x 300 = 60,000m2 Area = 150 x 350 = 52,500m2 Area = 100 x 400 = 40,000m2 Area = 50 ...read more.


I will now increase the number of sides on a shape and see if I can find a maximum area. I can see that as the number of sides increase the area also increases. The question now is does a circle have infinity sides, 1 single side or a peak number of sides n- sided Area = This formula shows that as n increases to infinity approaches tan 90 so that the angle between adjacent sides becomes 2x 90= 180o thus giving a circle. For a circle of a radius r = ...read more.

  1. The Fencing Problem

    One other thing we notice in the table is the last result which has an area of zero, although the perimeter is intact. This is an anomaly due to the fact that this triangle is physically impossible to draw; the sloping sides are too short to meet each other as the base is not shorter than both their lengths combined.

  2. The Fencing Problem.

    Having split the pentagon into isosceles triangles and then into right angled triangles I can now find the area. I know that the base of the triangle is 100m however I do not know the height. Before finding the height I must work out what the internal angle is.

    Isosceles and then an Equilateral After testing, analysing and evaluating the values for Equilateral, Isosceles and Scalene triangles I have come to a conclusion that a shape with all sides that are equal will have a larger area than a shape which has only 2 or more sides equal.

    Of Sides Interior Angle = 180�-Exterior Angle I will then use tangent of an angle, to work out the area of one of the one hundred segments of the shape. I will multiply this number by 100 because the 100 segments are all the same size.

    400 From this I can easily work out the height of the triangle by using Pythagoras's theorem because when splitting a isosceles triangle in two. The halves are always right angle triangles (see below). To work out the height I will use the equation below: Height2 = slant height2 - (base2/2)

    / n2. I then need to multiply this by 2n to get the overall area of the whole polygon. Then the formula would be 2n x ((125000 x Tan (90 - (180 / n))) / n2). This can be simplified to: (250000 x n x Tan ((90 x (n - 2))
