The hammer is an example of a machine when you take a nail out of a piece of wood. is a lever type 2.
professionally, how would you describe why the hammer has a long handle, and how that would result in a greater ideal mechanical advantage? please include the forumla of IMA = dl/de and use it for a better understanding

Please, first try to answer the question yourself.
Levers utilize a moment arm which can be used to increase the force applied to something or conversely to reduce the force input.
Please refer to this nice overview -

The hammer's long handle utilizes a moment arm which can be used to increase the force applied to something from a pivot. The hammer has a long handle because it increases the distance of effort. Since
Ideal Mechanical Advantage = Distance of Effort/ Distance of Load, the distance of load stays the same but the distance of effort increases, the mechanical advantage is greater
does that look good?
