where R is the resistance, p is the resistivity of the wire, l is the length and a is the area of cross section of the wire.
Assuming p to be constant,
We can see that R is directly proportional to length and inversely proportional to area of cross section i.e, R increases with increases with increase in length and R decreases with increase in area.
In short and thick wire, area is more and length is lesser. In long and thin wire, area is less and length is more.
Considering the above proportionality, long and thin wire will have higher resistance.

Because it's not the thickness of the object, it's the thickness of the electrical path. A thicker wire does not increase the thickness of the path but instead increases its length, thereby increasing resistance.
