Question

Bantu aku no 3 4 dan 5 pliss besok di kumpulin..

Answer 1

3.
a) 15-10 = 5
miring = √(12^2 +5^2) = 13
K = 13 + 15 + 12 + 10 = 50 cm

b) 24-12 = 12
kanan & kiri masing2 6 cm
miring = √(8^2 + 6^2) = 10
K = 10 + 12 + 10 + 24 = 56 cm

4.
a) 20-6 = 14
kanan & kiri masing2 7 cm
tinggi = √(25^2 - 7^2) = 24
L = (20 + 6) x 24 : 2
L = 26 x 12 = 312 cm^2

b) L = (14 + 8) x 8 : 2
L = 22 x 4 = 88 cm^2

5.
L = (s + s) x t : 2
100 = (s + s) x 10 : 2
100 = (s + s) x 5
20 = (s + s)

2 + 3 = 5
2/5 x 20 = 8 cm
3/5 x 20 = 12 cm

Ket: (s + s) = jumlah sisi sejajar

Answer 2

Aku cuma bisa jawab 4 soal. yang no 5 udah coba tp susah.
Semoga membantu yaaa :)


Semoga keliatan :")
