The pressure of a solid is calculated by the formula: p = F / S, where F is the force, S is the area. Let us express the area: S = F / p.
F = mg = 800 kg * 9.8 N / kg = 7840 N.
S = 7840 N / 15000 Pa = 0.52 m2.
Since the car has 4 wheels, the area of one wheel is 0.52 m2 / 4 = 0.13 m2.
Answer: 0.13 m2.
