we need to fence off a rectangular section of land in order to make some huge play pens. All four sides will be fenced and there will also be 2 parallel fence lines inside the perimeter in order to make 3 identical fields. If we have 2600 meters of fencing, we need to determine the dimensions for the entire fenced area that will produce an area of 100 000m^2

John wants to build a fence around his yard. The yard is 10 ft long and 18 ft wide. How much fence does he need?
