Gabriella needs 120 meters of fence to surround a rectangular garden.
iren [92.7K]

To fence a rectangular garden, we need to fence the length 2 times, and the width 2 times.

So, it will take 120 : 2 = 60 meters of fence to fence 1 length and 1 width

-> The length = 60 : (3+1)x3 = 45 (meters)
-> The width = 60 - 45 = 15 (meters)

Recheck : (45+15) x 2 = 120 and 45:15 = 3


(If it's wrong you can tell me, I don't really know what do you mean by how wide is the fence)
