An expensive fencing along the lot's length costs \$20 per foot and an inexpensive fencing along the two side widths costs only \$8 per foot. The total cost of the fencing along the three sides comes to \$5800. What are the lot's dimensions? Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!this is the 2nd time I have seen this problem, and the total cost is still not realistic let me help... ___ the maximum cost is if the lot has zero width (also not realistic) ___ 20 * 160 = 3200 ___ the minimum cost is with zero length (yeah, yeah; I know) ___ 160 * 8 * 2 = 2560 for this problem to yield real answers, the total cost must lie between the above values
