A farmer wants to fence a rectangular pasture using a river as one side. The pasture must contain 180,000 square meters of space for the herd to frolic. What is the least amount of fencing required to enclose such a pasture?

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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

no he doesnt because "-16' is negatiive
