1.
Total yield=(25+x)*(37-x)
=25*37+12x-x^2
Maximization occurs at 12-2x=0
=>x=6
So, Highest yield of (25+6)*(37-6)=961 pounds, 31 trees should be planted per acre
2.
Area=lb=1800
Cost of
fencing=(2l+b)*4+b*12=(2l+1800/l)*4+1800/l*12=8l+28800/l
Maximization occurs at 8-28800/l^2=0
=>l=(28800/8)^(1/2)=60.00
b=1800/60=30.00
