Answer:
12250 ft²
Step-by-step explanation:
Let x represent the length of a partition. Then the total length of that and all of the fence segments parallel to it will be 5x. The length of the side of the rectangular area in the perpendicular direction will be ...
(700 -5x)/2
Then the total area of the 4 pens is ...
Area = (x)(700 -5x)/2 = (5/2)(x)(140 -x)
This function describes a parabola opening downward, with zeros at x=0 and x=140. Its vertex (maximum) will be halfway between those zeros, at x=70.
Then the maximum area is ...
Area = (5/2)(70)(140 -70) = (5/2)(4900) = 12,250 . . . . ft²
