thereforeLong required: 12 meters.This is a formula.Such as a+b=12A=b=6, the product has a maximum value of =6 * 6=36.
Coop perimeter =20 x 1.2=24 MSet length is x, width is 1/2 (24-x)Area =x & 1/2 (24-x)=1/2 x (24-x)X+24-x=24 and for the fixed value, the product has the maximum value, and
Because reach the height of not less than 2 meters, so the metal net can set width, is placed sideways,
