tolonvdi jawab plizzz no 20-22 pakai cara plizzz!!!!

20) 3/4 ha+ 50 dam^2+ 20 are + 100 m^2
= 3/4×10.000+50×100+ 20×100 + 100
= 7.500 m^2+5000+2000+100
= 14.600 m^2
21) 40 m^3 = 40000 dm^3
40.000-35000 dm^3
= 5.000 dm^3
22) 30 detik = 2 liter
1 detik =1/15 liter
6 menit = 360 detik
360/15 =24 liter

20. 3/4 ha = 3/4 * 10.000 m² = 7500 m²
50 dam² = 5.000 m²
20 are = 2.000 m²
jumlah = 7.500 + 5.000 + 2.000 + 100
= 14.600 m² (D)

21. 40 m³ = 40.000 liter
40.000 - 35.000
= 5.000 liter (dm³)

22. Volume = debit x waktu
debit = 1 liter/15 detik
=debit x waktu
= 1/15 x 360
= 24 liter (C)
