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 $744, what is the length of the plot in meters?  Choose the correct choice from the following
A) 11  B) 13  C) 15  D) 17  E) 19
perimeter = 2L + 2W = 2L + 2(L-10) = 4L - 20   cost of fencing = (4L - 20) * 15.50 = 62L - 310 = 744   62L = 1054   L = 17 meters   The answer is 17.
