Starting with a 120​-foot-long stone​ wall, a farmer would like to construct a rectangular enclosure by adding 840 feet of​ fencing, as shown in the figure to the right. Find the values of x and w that result in the greatest possible area.

Starting with a 120-foot-long stone wall, a farmer would like to construct a 120 feet hown in the figure to the right. Find the values of x and w that result in the greatest possible area.

Find the local extreme values of L(x) = ln(x2 + 1). State carefully any tests that you use. A rectangular enclosure is to be constructed having one side along an existing wall and the other three sides fenced. If 100m of fencing is available, what is the largest possible area for the enclosure? At a certain instant, the length of a rectangle is Mini and tin- width is 12in. The width is increasing at 3m per second. How fast is the length changing if the area of the rectangle is not changing?
