jawab nomer 1,2,3,4 dan 5
Jawaban + Cara Penyelesaiannya
Nomer 1
L = a × t
L = 16 × 20
L = 320 cm²
Nomer 2
L = a × t
L = 20 × 8
L = 160 cm²
Nomer 3
L = ½ (p1 + p2) h
L = ½ × (28 + 18) × 12
L = ½ × 46 × 12
L = 552/2
L = 276 cm²
Nomer 4
L = s²
L = 15²
L = 225 cm²
Nomer 5
Luas belah ketupat = a × t
L = 18 × 18
L = 324 cm²
Luas trapesium = ½ (p1 + p2) h
L = ½ × (18 + 9) × (18 ÷ 2)
L = ½ × 27 × 9
L = 243/2
L = 121,5
Luas gabungan = L belah ketupat + L trapesium
L = 324 + 121,5
L = 445,5 cm²
