The photosynthetic rate of a leaf (in arbitrary units) is modeled by \(P(L) = 0.2L - 0.01L^{2}\), where \(L\) is the leaf area in cm\(^2\). Water loss from the leaf is given by \(W(L) = 0.05L\). The net benefit is \(B(L) = P(L) - W(L)\). Determine the leaf area \(L\) that maximizes \(B(L)\). Give your answer to one decimal place.
