A rectangular plot of land has dimensions $x$ meters by $y$ meters. The plot of land is 216 square meters in area. Farmer Ted encloses the rectangle with a fence and then divides the rectangle into two equal parts with another fence of length $x$ meters parallel to one of the sides. In terms of $x$ and $y,$ what is the total length of fence used? Describe the length of the fence used in terms of only one variable.

Total fence required = x + x + y + y + x = 3x+2y

x * y = 216 so 216/x = y sub this into the red equation

3x + 2 (216)/x = 3x + 432/x
