Verified answer
Sisi Bawah :Sisi Bawah = 18 m
Tinggi Trapesium 1 :
t = √5² - (12 - 8)²
t = √25 - 4²
t = √25 - 16
t = √9
t = 3 m
Tinggi Trapesium 2 :
Tinggi Trapesium 2 = 4,5 m
Luas Trapesium 1 :
L = ½ × JSS × t
L = ½ × (8 + 12) × 3
L = ½ × 20 × 3
L = 10 × 3
L = 30 m²
Luas Trapesium 2 :
L = ½ × JSS × t
L = ½ × (12 + 18) × 4,5
L = ½ × 30 × 4,5
L = 15 × 4,5
L = 67,5 m²
Luas Daerah yang Diarsir :
L = 67,5 m² - 30 m²
L = 37,5 m²
Jawaban : C. 37,5 m²
