Question #cfa4d

Answer 1

18 cm `^2`

Explanation:

`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`
