Answer:
w = 60 (width), l = 120 (length)
Step-by-step explanation:
Perimeter is when you take every side and sum it up.
So if we had a, b, c, and d sides the perimeter would be
P = a + b + c + d
In our case, we have 2 sides with 2*w
and 2 sides with w
P = w + w + (2*w) + (2*w)
And we also know that perimeter equals 360 meters
which leads to this
360 = w + w + (2*w) + (2*w)
360 = 2w + 4w
360 = 6w
w = 60
