## anonymous one year ago 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

(land of the large scale Farm ?) this is the last part of the question

hi!!

3. misty1212

i suck at geometry, but i have an idea

4. anonymous

5. misty1212

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

6. misty1212

you know $A=500$ and apothem = 10\

7. misty1212

$500=\frac{P\times 10}{2}$

8. misty1212

you can solve for the perimeter

9. misty1212

you should get that the perimeter is $$100$$ from the algebra

10. misty1212

once you get that, part 2 is just a multiplication

11. anonymous

you saying part 2 i should get 100

12. anonymous

i got part 1 now i need help with part 2 and 3

13. misty1212

part 1 is 100, the perimeter is 100

14. anonymous

do i do 100 times 7.95

15. misty1212

yes

16. anonymous

what do u suggest i do for part 3
