    9600

    Step-by-step explanation:

    We know that with rectangles, there are two equal sides. So let's say side A = side B and side C = side D. We know that one side is 60 meters, let's use side A for that. That means side B is also 60 meters. Together that is 120 meters out of the 200 available. Meaning, we have 80 meters left and two sides. Since we know the two sides left (side C and side D) are equal, we can just divide 80 by two. That gives us both side C and side D equalling 40 meters of fence. To find the area of the rectangle, we have to multiply all the sides together. So we have side A = 60 meters, side B = 60 meters, side C = 40 meters, and side D = 40 meters. Then we multiply. 60 times 60 times 40 times 40. This gives us the area of 9600 meters.

    Area=LW = (60m) (40m) = 2400 m^2
