Best ResponseYou've already chosen the best response.2Okay, so you have 682 feet of fencing to make up two "width sides" and one "length side" this translates to the equation: 682 = 2W + L You know from basic geometry that the area of a rectangle is length times width: A = L*W What you need to do is solve the first equation for L in terms of W: 682 = 2W + L L = 682 2W Then substitute that L value into the second function so that you have A in terms of just W: A = L*W A = (682 2W)W

Best ResponseYou've already chosen the best response.0your approximation doesn't have to be mine but both of ours should be pretty close to the same thing is yours close to my?

Best ResponseYou've already chosen the best response.0k now you remember the file i gave you right? that vertex of the parabola i found by putting the parabola in vertex form gave me the exact (max width,max area)
