Do you want the answer to the entire question or just the first part?

It is given that the initial area is 100 square inches, and the area reduces by half every time the paper is folded. So, what we have here is an exponential decay function. An exponential function is of the form y = ab^{x} where a is the initial amount, and b is the decay factor, and x is the independent variable.

Just plug in a = 100, b = \frac{1}{2}, and x=n to get the equation which will give the area.

Please have a look at this below discussion. It will help you understand what I just said.
