I need help with finding the resistivity (slope*area)Resistance and area

Resistance Vs. Length Area=0.50 cm^ 2 Resistance Vs. Length Length (cm) Resistance (ohms) 0.25 0. 1 0.006 y = 0.0593x + 1E-05 WN - 0.6 0.036 0.2 R2 - 1 0.95 0.056 ........ 1.4 0.083 2 0.15 1.69 0.1 2.38 0.141 0.1 2.82 0.168 3.07 0.182 0.05 .......56.. 3.56 0.211 10 3.91 0.232 0.5 1.5 2 2.5 3 3. 4 4.5 L (cm) Resistivity = Slope*Area 28 29 Resistance and area 30 31 32 Area (cm^2) 1/A (1/cm^ 2) Resistance (ohmn) 33 + 34 35 36 38 39
