#T_{PQRS}=a \cdot m_a=48# #T_{PQA}=\frac{a \cdot \frac{m_a}{2}}{2}=\frac{a \cdot m_a}{4} #
#T_{ARB}=\frac{\frac{a}{2} \cdot \frac{m_a}{2}}{2}=\frac{a \cdot m_a}{8} #
#T_{BSP}=\frac{\frac{a}{2} \cdot m_a}{2}=\frac{a \cdot m_a}{4} #
# \ Σ=\frac{5}{8} \ a \cdot m_a #
#T_{PAB}=\frac{3}{8} \cdot 48=18\ cm²#
