QUESTION $3$

$[10$ MARKS$]$

A civil engineering project involves the design of a water supply system for a catchment area. The catchment area has an average annual rainfall of $1200mm$ and an area of $500$ hectares. The evapotranspiration rate is estimated to be $800mm$ annually. Calculate the following:

$3\mathrm{.}1$ Total Precipitation over the catchment area in cubic meters.

$3\mathrm{.}2$ Total evapotranspiration from the catchment area in cubic meters.
