Cody's fence must have sides that are twice as long as the sides of his neigbore fence. His neigbors fence contains an area of 887.5 ft the length of the fence is

59.58 ft

Step-by-step explanation:

Given

The area of the neighbor's fence is  

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

So, we can write

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

The length of Cody's fence is

a

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
