F=20.81F = 20.81F=20.81 N correct to 2 decimal places P=5.12P = 5.12P=5.12 Nm−2^{-2}−2 correct to 3 significant figures
p=FA p = \frac{F}{A} p=AFp=p =p= pressure, F=F =F= force, A=A =A= area
By considering bounds, work out the value of A A\,A to a suitable degree of accuracy. Give a reason for your answer.
