So perimeter<u><</u>556 permiter=2Legnth+2Width so perimiter=2(legnth+width)
556/2<u>></u>Legnth+width 228<u>></u>legnth +width legnth =150 so 228<u>></u>150+width subtract 150 from both sides 78<u>></u>width width cand be 78 or less but not 0 or negative
anoth way to do it is 556<u>></u>2(150)+2width 556<u>></u>300+2width subtract 300 from both sides 256<u>></u>2width divide both sides by 2 78<u>></u>width
