How to solve this question 

Three resistors are made out of three different materials and
Material 1
0.00367 2-m
have different (but uniform) cross sections. Resistor 1 has a
Material 2
0.488 2-m
circular cross section of radius 2.90 mm. Resistor 2 has a
Material 3
7.99 x 10- 2-m
square cross section with a side length of 2.22 mm. The third
resistor's cross section is a right triangle with two sides of
length 5.50 mm. All of the resistors are 0.913 cm in length.
Use the provided table of resistivities to calculate the
resistance of each resistor.
R| =
Ω
R2 =
Ω
R3 =
