L = 2 W
Perimeter = L+W + L + W
Perimeter = L + 2L + L + 2L
P = 6L
18 = 6L
3 = L
W = 6.

You solve for the width. You have in the perimeter 2 lengths, which being twice the width yield 4 widths and other 2 widths, in total 6 widths. Divide 18ft by 6 and you have the width = 3ft. The length is double i.e. 6ft.

2*length + 2*width = 18ft.
2*width = length
2*(2*width) + 2*width = 18
4*width + 2*width = 18
6*width = 18
width = 3ft
2*width = length
2*(3ft) = length
length = 6ft

2a + 2b = 18 '
2 (a+b) = 18'
a + b = 9'
a = 2b
2b + b = 9'
3b = 9'
b = 3'
a + 3 = 9'
a = 6'

2(2x+x)= 18
2x+x=9
3x=9
x=3
Length is 3 ft and width is 6 ft
