Question

Tolong jawab kan 1-6 tolongya

Answer 1

1. luas = (1/2 x 3 x 4) x 10 = 6 x 10 = 60 cm2
2. luas = (3.14 x 4 x 4) x 30 = 50.24 x 30 = 1507.2 cm2
3. luas = 10 x 5 x 6 = 300 cm2
4. luas = 1/3 x (22/7 x 14 x 14) x 10 = 1/3 x 616 x 10 = 20 cm2
5. luas = 4 x 4 x 4 = 64 cm2
6. luas = 2 x (luas segitiga 1 + luas segitiga 2) = 2 x ((1/2 x 10 x 8) + (1/2 x 5 x 9)) = 2 x (40 + 22.5) = 2 x 62.5 = 125 cm2

maaf kalau salah
