A stone wall surrounds a rectangular plot with 510 feet of stone. The length of the plot is 3 less then twice the width of the plot. Find the length and width of the plot.
Let W = width of the plot.
Let L = length of the plot.
L = 2W - 3
Total perimeter = L + W + L + W
510 = (2W - 3) + (W) + (2W - 3) + (W)
510 = 6W - 6
516 = 6W
86 = W
L = 2W - 3 ---> L = 2(86) - 3 = 169
