tolong ya semuanya thanks

1 are = 100 m^2 = 1 dam^2.
1 ca = 0,01 are

2500 m^2 + 100 dam^2 - 150 ca = 25 are + 100 are - 1,5 are = 123,5 are. (Jawaban C)

1 m² = 1 ca

• 2.500 m² ➡ 2.500 ca

• 100 dam² ➡ 100 x 100 = 10.000 m²
• 10.000 m² ➡ 10.000 ca

• 150 ca

= 2.500 ca + 10.000 ca - 150 ca
= 12.250 ca

= 12.250 ca = 12.250 : 100
= 123,5 are
