Oh wait, I read it wrong, sorry.

width --- x
length -- x+7

2(x + x+7) = 140

easy to solve...

and I read it wrong as well, lol

width --- x
length -- 2x+7

2(x + 2x+7) = 140

P=2(l+w)
width=w
length=2w+7
(w)+(w)+(2w+7)+(2w+7)=140
6w+14=140
6w=140-14
6w=126
w=126/6
w=21(width)
l=2w+7
2*21=42+7=49 (length)
