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
