KatRina [158]

Answer: 59.58 ft

Step-by-step explanation:

Given

The area of the neighbor's fence is $A=887.5\ ft^2$

Suppose the length of the fence is L and the shape of the fenced area is square

So, we can write

$\Rightarrow L^2=887.5\\\Rightarrow L=\sqrt{887.5}=29.79\ ft$

According to the question, Cody's fence length must be twice of neighbor's

The length of Cody's fence is $=2L=2\times 29.79=59.58\ ft$
