Tolong jawaban nya dan cara nya

Answer 1

Diket :
Lt = 390 m^2
A1 = 2/3 bagian
A2 = 1/6 bagian

ditanya : A3...?
jawab :

• A1 + A2 + A3 = 1
• A3 = 1 - [(2/3) + (1/6)]
• A3 = 1 - [(4+1/6)]
• A3 = 1 - (5/6)
• A3 = 6/6 - 5/6
• A3 = 1/6
• A3 = 1/6 bagian

•> A3 = (1/6) × Lt
•> A3 = (1/6) × 390
•. A3 = 65 m^2 #D

Answer 2

Luas tanah 390 m3
anak pertama 2/3
anak kedua 1/6

anak ketiga
= 1 - 2/3 - 1/6
= 6/6 - 4/6 - 1/6
= 1/6

1/6 × 390 = 65 m3
