Length of a Hammer

[hsm3084]

I have no idea where to get started doing this problem.
The head of a hammer is located 9 cm to the left of its center of mass, while the bottom of the handle of the hammer is 29 cm to the right of the center of mass. Determine the length of the hammer. Justify your answer using an appropriate geometry principle (definition, theorem, etc.).

Draw a diagram and mark points and dimensions given in the problem.

if I were to solve this problem - I would first have a line sketch of the problem - the length of the line representing the length of the hammer. Put a point C on the line representing the centre of the mass. Assume the head of the hammer to be at one of the end-point of the line.

Now think and share your thoughts/work with us.

Ugh - a minute late I was.....

I got that the length of the hammer is 38 cm by adding 29 and 9 but I don't understand how to justify my answer using a geometric principle.

To the corner, you should go. Hmmm?

Please list the geometric principles and theorems you have been taught.
