Good day to all of you Honorable Engineers,i am a bit lost with how to attempt this calculus problem,it goes like this "A mining company has 10 000 meters of fencing available.It wants to use the fencing to enclose a rectangular field.One side of the field is bordered by a river .If no fencing is placed on the side next to the river,what is the largest area that can be enclosed?
i assumed my width to be 'x',then divided the field into 3 parts to get the length as a function of width and got this expression: Length=(10 000-3x)/2,but this is where i get lost because the other side of the field that borders the river will not be fenced ,so how can i then derive my equation without the other side being fenced?
