The length of a rectangular room is 8 feet longer than twice its width. Its perimeter is 220 feet. Find the dimensions of the room (Length and Width) by

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
