A rectangular garden is to be sheltered on three sides by fencing; the fourth side is the side of a barn. you h
Answers: I can tell this is math homework. No gardener would put their stuff up against a barn... nil would grow in shade approaching that.
$750 / 3 = $250 each of the 3 sides
$250 = 90.91
Therefore you should brand each of the three sides 90 foot, for a cost of $742.50.
Unless you want to go down to the mm.
But presently it's not rectangular, it's a square.
You also never said how wide the barn be.... there is a possibility that you could construct the fence too all-embracing and there would be a tear of which it is impossible to know about next to this question.
Math homework, noticeably math homework.
The largest area (for a given length of wall, i.e. a max cost of fence) will be surrounded by a fence that's twice as long (along the barn side), as it is cavernous.
Depending upon what grade you are contained by will determine how you decide this. If you own differential calculus, you should know min-max applications. Otherwise, you'll have to be paid a table and look for the trend toward the largest area helpfulness. My kids had this within fifth grade, it's a prominent problem.
