: A rectangular dog pen is twice as long as it is wide. The perimeter of the pen is 36ft. Find the length and width of the pen.
W=width
w x 2=length
P=2l + 2w
p=36= 2 (w x 2)+ 2 x w
36= 2w x 4 + 2w
36= 4w x 4

"p=36= 2 (w x 2)+ 2 x w" ___ this is OK

"36= 2w x 4 + 2w" ___ this is not ___ the parentheses caused a problem??
___ distributive law not needed for multiplication __ just remove parentheses and multiply

36 = 4w + 2w ___ 36 = 6w ___ 6 = w
