A and B are two square plates of same metal and same thickness but length of B is twice that of A . Ratio of resistances of A and B is

Two conducting wires A and B are made of same material. If the length of B is twice that of A and the radius of circular cross-section of A is twice that of B, then resistances R_(A)" and "R_(B) are in the ratio

If A and B are two square matrices of the same order, then A+B=B+A.
