The radius of the garden before change=5(since 5x5=25). 5+2=7, which is the new radius of the garden.

To get the amount of fencing needed, you first need to find the diameter and the resulting circumference.

D=2r, r=7, therefore D=14. C=D¥ð, so the circumference is 14¥ð.

That's about 43.9 meters.

Therefore you need 44 meters of fences, which is 44 fences.
