Verified answer

T trapesium
= √[(5 cm)² - {1/2 × (13 cm - 7 cm)}²]
= √{(5 cm)² - (1/2 × 6 cm)²}
= √{(5 cm)² - (3 cm)²}
= √{(5 cm)² - (3 cm)²}
= √(25 cm² - 9 cm²)
= √(16 cm²)
= 4 cm

V bangun = L a bangun × t bangun
V bangun = L trapesium × t bangun
V bangun = 1/2 × jumlah sisi sejajar trapesium × t trapesium × t bangun
V bangun = 1/2 × (7 cm + 13 cm) × 4 cm × 20 cm
V bangun = 1/2 × 20 cm × 4 cm × 20 cm
V bangun = 800 cm²
