Maximum Area A rancher has 400 feet of fencing with which to enclose two adjacent rectangular corrals (see figure).What dimensions should be used so that the enclosed area will be a maximum?

To determine

To calculate: The dimensions of the field such that its area would be maximum.

Explanation of Solution

Given:

The rancher has only 400 ft of fencing material available.

The field looks like:

Formula used:

For a function f that is twice differentiable on an open interval I, if f'(c)=0 for some c, then,

If f''(c)>0 the function f has relative minima at c if f''(c)<0 the function f has relative maxima at c.

Calculation:

From the provide figure, the field would have length of 2x feet and a breadth of y feet. Thus the area of the field that needs to be maximized would be:

A=2xy

Now the man has one 400 feet of fencing wire. This implies that the perimeter of the fencing area would be 400. Hence,

4x+3y=4003y=400−4xy=400−4x3

Replace this in the area to obtain:

A(x)=2x(400−4x3)=800x3−8x23

Equate the derivative with respect to x to zero to find the critical points:
