A farmer wants to put up a rectangular fence around his property. He wants to the length to be three times the width. What should the length of his rectangular fence be if he has 800' of fencing?
The length should be 300'. To solve this, let X=width and use the equation: X + 3X + X + 3X = 800' ---> 8X = 800' ---> X = 100', so the length is 3X ---> 300'.
