Answer 2

Luas Trapesium  ABCF = 1/2 × (panjang atas + panjang bawah) × tinggi
= 1/2 × ( 15 cm + (15 cm + 8 cm+ 8cm)) × ( t² = 10² - 8²)
= 1/2 × ( 15 cm + 31 cm ) × (t² = 100 - 64 = 36)
= 1/2 × ( 46 cm ) × ( t = √36 = 6 cm )
= 1/2 × 46 cm × 6 cm
= 138 cm²
Luas Δ FDE = 1/2 × a × t
= 1/2 × 16 cm × (t =√ 17 cm² - 8 cm²)
= 1/2 × 16 cm × 15 cm
=120 cm²
Jadi , luas bangun abcdef adalah 138 cm² + 120 cm² = 258 cm²
