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 $806, what is the length of the plot in meters?  Choose the correct choice from the following:
A) 16 B) 18 C) 20 D) 22 E) 24
perimeter = 2L + 2W = 2L + 2(L-10) = 4L - 20   cost of fencing = (4L - 20) * 15.50 = 62L - 310 = 806   62L = 1116   L = 18 meters   The answer is 18.
