None of the above.
The length of a rectangle is one unit shorter than one-sixth of the width, x mean:
L = W / 6 - 1
P = 2 L + 2 W = 2 ( L + W )
P = 2 [ W / 6 - 1 + W ] =
2 [ W / 6 - 1 + 6 W / 6 ] =
2 ( 7 W / 6 - 1 ) =
2 ∙ 7 W / 6 - 2 ∙ 1 =
2 ∙ 7 W / 2 ∙ 3 - 2 =
7 W / 3 - 2 =
7 W / 3 - 2 ∙ 3 / 3 =
7 W / 3 - 6 / 3 =
( 7 W - 6 ) / 3
P = 7 W / 3 - 2 = ( 7 W - 6 ) / 3
L = W / 6 - 1
P = 2 L + 2 W = 2 ( L + W )
P = 2 [ W / 6 - 1 + W ] =
2 [ W / 6 - 1 + 6 W / 6 ] =
2 ( 7 W / 6 - 1 ) =
2 ∙ 7 W / 6 - 2 ∙ 1 =
2 ∙ 7 W / 2 ∙ 3 - 2 =
7 W / 3 - 2 =
7 W / 3 - 2 ∙ 3 / 3 =
7 W / 3 - 6 / 3 =
( 7 W - 6 ) / 3
P = 7 W / 3 - 2 = ( 7 W - 6 ) / 3
