Fluids--Pressure. Help needed...

I've read the chapter in my book on fluids but I'm still not understanding my homework... I have a few problems that are--from what I can tell--the basic concepts of what all of the other problems are based off of. If someone could tell me how I need to go about doing these, it would be a great help. I'm not asking you to do my homework for me; just point me in the right direction with examples/explanations on why what does what so I can understand this stuff a little bit better.

If someone could help me out with one or both of these problems, I'd really appreciate it! Thanks.

1. Given : both exert the same pressure. What is the definition of pressure ?

2. How do you find the pressure in a liquid column, at some particular height ?

P=F/A

...but the I would have F/A=F/A and I don't know anything for either side of the equation..?

...and number 2 I might be able to work out, I'll just have to give it some time...

1. A = area of contact. What is the shape of this area in both cases ? What is the formula for the area of this shape ?

F = force. What is the force due to ? What is the formula for this force ?

2. Simply Googling "pressure in liquid column" will get you started, but really, this should be covered in your text.
