A \(10\ \text{m} \times 10\ \text{m}\) quadrat in a savanna contains 45 trees whose total basal area is \(180\ \text{m}^2\). A larger survey area of \(5\ \text{km}^2\) is to be estimated using the quadrat data, assuming the same tree density and average basal area per tree. A recent fire reduces tree density by \(18\%\) but increases the average basal area of surviving trees by \(9\%\). Estimate the total basal area of trees in the \(5\ \text{km}^2\) area after the fire, expressing your answer in hectares (1 ha = 10 000 m²).
