Plans call for the reptile Reserve to be surrounded on all sides by a fence. What is the total length of the fence?
Oduvanchick [21]

Answer:

There are no enough information to determine the length of the fence, assuming we were given the perimeter of the fence, and say, the dimension of the fence, then we can easily find the length.

Perimeter of the fence, P = 2(L + B).. If the fence is a rectangular.

L = (P/2) - B

If the fence is square, P = 4L

L = P/4
