you need to create a fenced off region of land for cattle to graze. The grazing area must be a total of 500 square feet, surrounded by a fence, and in the shape of a regular polygon. Within this grazing area, the length of the apothem must be 10 feet long.Part I. Find the total perimeter of the grazing area.Part II. If the cost of the fence is $7.95 per linear foot, how much will it cost to place a fence around the entire grazing area?Part III. Suppose this grazing area is of an industrial grazing area for a major industry farm. What is the total cost to build a fence around the entire land

    the area of a polygon is \[A=\text{perimeter}\times \text{apothem}\div2\]

    you know \[A=500\] and apothem = 10\

    \[500=\frac{P\times 10}{2}\]

    you can solve for the perimeter

    you should get that the perimeter is \(100\) from the algebra
