As per the question
L = length = 2W-5
W = width
again 2(L+W) =230
2(2W-5+W) =230
or 4W-10+2W=230
or 6W=240
or W = 240/6=40
so L=2*40-5=75
so length = 75 ft and width = 40 ft

First you need the Formula for a Rectangle which is P=2%28lxW%29 or P=l%2Bw%2Bl%2BW
Width = x
Length = 2x-5
230+=+2%28x%2B2x-5%29
230=2x%2B4x-10
230=6x-10
230%2B10=6x
240=6x
40=x
Check you answer by pluggling 40 into x
230=2%2840%2B80-5%29
230=80%2B160-10%29
230=230
Width = 40
Length = 75
I hope that helps you
