So the maximum area would be 450? I'm trying to read through your work so I can understand how you got the answer

Nope I still don't get it. I understand right up until this... " w^2 - 30 w = -A/2 w^2 - 30 w + 225 = -A/2 + 225 (w-15)^2 = -(1/2)(A - 450) so w = 15 L = 60 - 30 = 30 area = 450 by the way " Thanks anyway!
