Question 1081759: a mpumalsnga farmer needs to buils a rectangular enclosure with 50m of fencing on one of the sides of the enclisure there is a wall find the dimension of the enclosure which will give the maximum area

The two sides are x
The long side is 50-2x
They add to 50
the area is x(50-2x)=50x-2x^2
That is a parabola with vertex -b/2a for x value, which is at -50/-4=12.5
x=12.5 m on two sides
2x=25 m long side
area is 312.5 m^2
Try 24 and 13, area 312 m^2
try 26 and 12, area 312 m^2
