What is the total cost of the fencing materials?

skip is fencing in a square area of 576 square feet. Fence posts, which are needed every three feet, cost $32 each. the fencing itself costs $4.50 per foot.|||the area is x虏 = 576 where x is the length of one of the sides


so x = 鈭?76 = 24


there are four sides so the total length of the fence is


4*24 = 96ft


at $4.50 per ft


so the cost of fence is


96*4.50 = $432.00





the posts are each 3ft apart and the length of fence is 96ft


so there are


96/3 = 32 posts


so the cost of posts is


32*32 = $1024.00





add the fence price to the posts price you get the total cost as


432 + 1024 = $1456.00





,,.,.,.|||Fence = root576 x 4 x 4.5=432





Posts = (root576/3) x 4 x 32= 1024


Sorry! Imissed the Square area note first!





If you go on EBay though you can get it cheaper!|||area = s^2


576 ft^2 = s^2





s = 24 ft


P = 4s = 4(24) = 96 ft





cost of fence = (96 ft )($4.50 / ft) = $432





cost of post = (96 ft / 3 ft)(32) = $1024





total cost = $432 + $1024 = $1456





=)|||Hej lalabt,


a square of 576 sq.ft. has sides of length 24 ft.


So the fencing costs 24 x $4.50.


On one side of 24 ft. you need 8 posts (check that!)


4 sides, so you need 4 X 8 = 32 posts.of $32 each, so...|||Area of a square is a^2





so a=24 (sqrroot(576)).





now the perimeter of the square is





4a





so


fencing 4*24 feet costs,


4*24*4.50=$432








now no of posts needed = perimeter/3





=4*24/3=32








hence cost for the posts = 32*32=$1024





so





the total cost = 1024+432=$1456
