Answer:
1200 m
Step-by-step explanation:
We are given that
Area of pasture,A=180000 square meter
We have to find the least amount of fencing required to enclose such a pasture.
Let length of pasture,=x
Width of pasture,b=y
Area of pasture=
Fencing required=2x+y
Differentiate w.r.t x
m
It is always positive because length cannot be negative.
m
Again differentiate w.r.t x
Substitute x=300
The fence is minimum at x=300
Therefore, fencing required to enclose such a pasture
1000 if rounded to nearest thousand
At T=4, y = 54. Hope I was able to help
