Perimeter = 2(l + w)
Thus,
102 = 2(l + w)
l = 6 + 2w
102 = 2( 6 + 2w + w)
102 = 12 + 4w +2 w
102 = 12 + 6w
90 = 6w
Thus, w = 15.
Length = 6 + 2w
= 6 + 30
= 36.
Thus, the length is 36 meters and width is 15 meters.

Answer: 6x - 6
Step-by-step explanation: 2x + 6 + 4x - 12
2x + 4x = 6x
6 - 12 = -6
= 6x - 6
