Bounds

\text{ N correct to 2 decimal places}

\text{ Nm}^{-2} \text{ correct to 3 significant figures}

\frac{F}{A}

$p$ = pressure, $F$ = force, $A$ = area

a.

Write down the lower and upper bounds for $F\,$ and $P$ .

[1]

b.

Hence, by considering bounds, work out the value of $A\,$ to a suitable degree of accuracy. Give a reason for your answer.
