A kennel owner would like to design a set of dog runs that contain a total area of 640 sq. ft. The area will consist of 4 adjacent identical rectangular runs against the back wall of the building (no fence needed against building). The front of the fence (parallel to the building) must be made out of material that costs $12.50 per foot. The side and interior divider material costs $8 per foot. State animal regulations require that the runs be at least 4 feet wide in any direction. What dimensions will minimize the cost of the fencing?

2. A farmer wants to fence in a rectangular plot of land. The north end already has a wall and doesn't need any fence. The neighbor to the west will split the cost of the fence on the west end. The fencing costs $16 per foot to install. a. If the farmer has $4,800, find the dimensions for the plot that would enclose the most area. b. If the farmer wants to enclose 60,000 square feet of land, what dimensions will minimize the cost of the fence?

A farmer wants to fence in a rectangular plot of land adjacent to the north wall of his barn. No fencing is needed along the barn, and the fencing along the west side of the plot is shared with a neighbor who will split the cost of that portion of the fence. If the fencing costs $20 per linear foot to install and the farmer is not willing to spend more than $500, find the dimensions for the plot that would enclose the most area. If the farmer wants to enclose 8000 square feet of land, what dimensions will minimize the cost of the fence? Please show steps!
