Fence Fencing
A farmer wants a pasture near rectangular along the banks of a river. The grazing land is that?
A farmer wants to close a rectangular pasture along the river bank. The pasture area is 3200 square feet and no fence is needed along the shore. Find the dimensions of the pasture require less fencing. The fence is available in 150 m
The grazing has a width W and length L (parallel to the river) requires the full closure is L + 2 W = 150 or L = 150 – 2W Area = W = W * L (150 – 2 W) is a parabola that opens downwards, with zeros at 0 and 75 in the mid-way summit to be among them, 37, 5, if w = w = 37.5, L = 150 – 75 = 75 maximum size is 75 by 37.5 = 2812.5 as the maximum area of 150 meters of the fence is 2812.5, you can not enclose an area 3200 ***** However, if the question is: what is the minimum amount required to enclose an area of 3200: A = L * w L = 3200 = 3200 / W and fences need is: F = 2W + 2W + L = 3200 / F w = 2 – 3200 / W ^ 2 of fencing will be a minimum when F '= 0 ==> 2 = 3200 / ww ^ 2 ^ 2 = 3200 / 2 = 1600 W = 40 W = 40, then L = 80 (minimum of 160 meters of fencing is needed for an area of 3200
