well generally the independent variable is the one you vary, and dependent is the one whose value DEPENDS on the independent variable.
like for example if you have V=IR, with constant I
varying R, will change the value of V
so R is the independent value and V is dependent

how do we know which is the dependant and independant variable?? =\

It says in the question that the student is given sheets of glass of different areas.
'Independent variable' is something that you can vary, which the 'dependent variable' depends on..
So here, you can varying the the area of the glass will have an effect on the resistance, therefor R depends on A.
So R is the dependent.. and A the independent..
Hope you understood what I mean :)
