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.

    This can be found by excluding 1800 from the exterior angle. Interior angle = 1800 - Exterior angle Interior angle = 1800 - 60 = 1200 Now by using the help of the interior angle I have calculated I shall find of the angles within one of the five triangles that can be made in a regular pentagon.

    250 250 500 Nevertheless, I have noticed that the difference between the highest value and the values either side of it is quite large. Therefore, I can further develop this analysis by producing another set of data, this time increasing the base values by a much smaller-scale number such as 10.

    minus all of the exterior lengths I have discovered so far from 1000 m and then divide the answer by 2 to give me the length of one side. * 1000 - 100 - 100 - 70.71067812 - 70.71067812 = 658.5786438 * Now that I have the side length of

    Pentagon Pentagons have 5 sides therefore I can divide it up into 5 isosceles triangles, and the angle at the top an isosceles triangle would be 360/5=72?.Therefore the other angles = (180-72)/2=54? each. I can split the isosceles triangle into 2 equal right-angled triangles and work out the area of the triangle, using trigonometry.
