Answer:
length=76 width=34
Step-by-step explanation:
to get the length on one side the equation is 2w+8 and the width is w so times them both by two to solve for all sides it is:
2w+8+2w+8+w+w which simplifies to 6w+16
if the perimeter is 220 it is 6w+16=220
you then minus 16 from both sides and get: 6w=204
next you divide both sides by 6 to get w= 34
if w=34 on one side and the length is 2w+8 you substitute the w for 34
2(34)+8 which equals 76
