The length of a rectangular plot is 10 meters more than its width. If the cost of fencing the plot at $15.50 per meter is $682, what is the length of the plot in meters?  Choose the most appropriate option.
A) 10  B) 12  C) 14  D) 16  E) 18
perimeter = 2L + 2W = 2L + 2(L-10) = 4L - 20   cost of fencing = (4L - 20) * 15.50 = 62L - 310 = 682   62L = 992   L = 16 meters   The answer is 16.
