Mohon bantuannya no 28,makasih

Panjang SR :
[tex] \frac{8}{8 + 4} = \frac{6}{sr} \\ 8sr = 6 \times 12 \\ 8sr = 72 \\ sr = 72 \div8 \\ sr = 9[/tex]

Panjang PQ :
[tex] \frac{8}{8 + 4} = \frac{20}{pq} \\ 8pq = 20 \times 12 \\ 8pq = 240 \\ pq = 30[/tex]

Luas Trapesium PQRS :
L = ½ × JSS × t
L = ½ × (30 + 9) × 12
L = 39 × 6
L = 234 cm²

Jawaban : C. 234 cm²

Maaf Kalau Salah
