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