**Damon**, Tuesday, January 22, 2008 at 8:59pmcall width w

then length = (w+2)

perimeter = 2 w + 2(w+2)

I think you can get it from there

**Jason**, Sunday, November 14, 2010 at 4:56pmw = width

l = length

p = perimeter

p = 2w + 2(2w + 2)

34 = 2w + 4w + 4 - distributive property

34 = 6w + 4

30 = 6w - move the 4 to the other side

30/6 = 6w/6

5 = w

to check that

w + w + (2w + 2) + (2w + 2)

5 + 5 + (2(5)+ 2) + (2(5)+ 2)

10 + 12 + 12

=34
