hibtubglah luas nya ! tolong pakai cara !

Luas Trapesium :
L = ½ × JSS × t
L = ½ × (20 + (20 - 6)) × 15
L = ½ × (20 + 14) × 15
L = ½ × 34 × 15
L = 17 × 15
L = 255 cm²

Luas Layang Layang :
L = ½ × d1 × d2
L = ½ × (2 × 6) × (8 + 15)
L = ½ × 12 × 23
L = 6 × 23
L = 138 cm²

Luas Gabungan :
L = 255 cm² + 138 cm²
L = 393 cm²

Maaf Kalau Salah
