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.
+37165 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
