Step-by-step explanation:
You haven't mentioned pressure I've seen it somewhere as 15 kgwf.
# Answer- 196 cm^2
# Given-
Weight of car = 1200kg
Pressure in each tyre = 15kgwf/cm^2
# Solution-
Total force exerted by car on ground
=1200×g
=1200×9.8
=11760 kgwf
Force on each tyre
= F/4
= 11760/4
= 2940 kgwf
Area of tyre
= Force/ pressure
= 2940/15
= 196cm^2
Area of each tyre is 196 cm^2.
