tolong ya jawab bo 1 - 9 aja pakai cara besok dikumpul

1. 1/2 x a × t = 1/2 × 48 × 36 = 864 cm persegi
2. 42 + 18 ×24 / 2 =720
3. 216÷36 = 6 (panjang alas = 6 cm )
4. 180÷4 =45 cm
5. jika gk dipotong :
= 18+ 28 × 12 / 2
= 46×6 =276 cm persegi
jika dipotong :
= (18 × 12) + (1/2 × 10 × 12)
= 216 + 60
= 276 cm persegi
6. (15×40) + (20×7)
= 600 + 140 = 740
7. 1/2 ×22/7 × 14 × 14
= 1 × 11 × 2 × 14 = 22 × 14 = 308
8. 22/7 ×7×7 = 154
= 770 ÷ 154 = 5
9. 1/2 × 5×12×8
= 30 × 8 = 240

Maaf Kalau Salah Ya .....

1. L: ½*a*t
: 24*36
:864 cm²
2. L: (a+b):½*t
:(18+42):2*24
:60:2*24
:30*24
:720 cm²
3. L. segitiga : ½*a*t
L :316 :1/2*a*36
L :316 :a*18
316 : 18. :a
12 :a
a :12 cm²
MAAF CUMA 3 AJA PENTING SUDAH DIJAWAB SAYA CAPEK KALAU SEMUA DIJAWAB
