The width of the room if the length is 18m is 1.66m.
We have given that,
Perimeter=60 and length=18m
P=2(l+w)
Where the l is the length and
W is the width
Perimeter=60 and length=18m.
Use this value in the formula of perimeter
60=2(18×W)
Divide both sides by 2
30=18w
isolate the w
Therefore, divide both sides by 18.
30/18=w
W=1.66m
Therefore the width of the room if the length is 18m is 1.66m.
