Question 763422: A rectangular dog pen is twice as long as it is wide. The perimeter is 36ft. Find the length and width Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Width = x
Length = 2x
Perimeter = 2*length + 2*width
36 = 2(2x) + 2(x)
36 = 4x + 2x
6x = 36
x = 6ft
Width = 6ft
Length = 12ft
Hope this helps.
