Find the exact total area of regions \(A\) and \(B\). Give your answer in the form \(k \ln m\), where \(k\) and \(m\) are constants.
Deduce an approximation to the area of region \(B\). Give your answer correct to 3 significant figures.
State, with a reason, whether your answer to part (c) is an over-estimate or an under-estimate of the area of region \(B\).
