Welcome to PF. Could you show your working an intermediate steps, please. You are more likely to be helped if you do this, since people will be able to follow your working rather than do it themselves.

I assume that each tire supports 1/4 of the weight of the car and that works out to be 3750N.I convert the tire pressure from 225KPa into N/sq.meters and do the equation A=F/P. This gives me 0.01666sq.meters. All of which I am doing in SI and rounding with significant digits. I just don't know how to type that.
That looks fine to me.
