Answer:
6 feet
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w
where l is the length and w the width
here perimeter = 34 and length = 11, hence
2 × 11 + 2w = 34
22 + 2w = 34 ( subtract 22 from both sides )
2w = 12 ( divide both sides by 2 )
w = 6
That is the width of the room is 6 feet
