Verified Answer :

P = 2(l+w)
120 = 2(35+w)
120/2 = 35+w
60 = 35 + w
60 -35 = w
25 = w

so width = 25

answer is b. 25 meters

As you know
Perimeter=2(l+w)
120=2(35+w)
120/2=35+w
60=35+w
60-35=w
w=25 meters


And if you want to CHECK your answer
find the perimeter simply with the width that we got.
P=2(l+b)
2(35+25)
2(60)
12 meter^2
