P=260
Length=30 greater than width...so set the width as X, and set the lenth as (X+30)

P=2L+2W
260=2(x+30)+2(X)
260=2x+60+2x <--subtract 60 from both sides
(260)-60=(2x+60+2x)-60
260=4x <--divide both sides by 4
260%2F4=4x%2F4
65=x

since the width=x, it is 65 meters long
the length=x+30 or (65+30=95), it is 95
