Thread: I am confused on the steps for optimization, could someone please help

Here is the sample problem (but the object will change for the test):

Optimization.The base b and height h of an isosceles triangle vary in such
a way that its perimeter,is constant,and equal to 6. Find the maximum possible area of the triangle.

What I know from this:
P=B * 2S (base times the 2 sides)
P=6
A=BH (base times height)

From the question I also think that I will be needing to find f' and f'' to find the maximimum area for the triangle, but I am not sure on that.

I always get confused on the steps to work through optimization word problems. Can someone please help? I understand more if there is a step by step process to solve something.

As a start, try this:
Perimeter = b + s + s = 6
Area =

s =

I also think that I will be needing to find f'

You are thinking right.
