For the largest area, half the fence is used parallel to the river, and the other half is used for the two ends of the rectangular space.
The dimensions are 475 m by 237.5 m.
_____
Let x represent the length along the river. Then the area (A) is found as
.. A = x*(950 -x)/2
This equation describes a parabola with its vertex (maximum) halfway between the zeros of x=0 and x=950. That is, the maximum area is achieved when half the fence is used parallel to the river.

The answer is 15000
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000
