P = 2W + 2L
...length is twice as long as width,
therefore
L = 2W
Substitute
P = 2W + 2(2W)
P = 2W + 4W
P = 6W
60 = 6W
W = 10
L = 2W
L = 20
ANS L = 20, W = 10
_______________________
Or use ratios
L:W = 2:1
2 + 1 = 3 parts
W = 1 part = 60/3 = 20
L = 2 parts = 40
There are 4 sides with 2 L's and 2 W's, so divide each by 2
W = 20/2 = 10
L = 40/2 = 20

You are 18. Why are your simple algebra abilities so poor ?? No math skills, no high paying job.

Man wants to fence around a rectangular garden, length is twice as long as width, what are the garden's dimensions if the perimeter is 60?
l + w = 30
l = 2w
width = 10
length = 20
Bone Alone
Length = 20
Width = 10

10x20. I think.
