How does the resistance of a piece of metal change if both its length and its diameter are reduced to one half their original values?

Question 1 answers

It is increased to 4 times the original value

It doubles

It remains unchanged

It is halved

It is reduced to 1/4 of the original value

2. Relevant equations

R = pL/A where P is the resistivity constant

3. The attempt at a solution

I am not sure how to relate the area to change in area
