Fencing = 3x + 4y 336 = 3x + 4y Area = 2xy A = 2xy x = (3364y) / 3 A = 2[(3364y)/3] y Find dA/dy and equate to 0. solve for y.

I dont understand this part: x = (3364y) / 3 A = 2[(3364y)/3] y Find dA/dy and equate to 0. solve for y.

i rearranged the fencing equation in terms of x and subbed it into the area equation. find the derivative of A with respect to y. make it equal 0. solve for y. sub y into original equation and solve for x.
