Tolong bantu no 9,10,11 dengan cara yah

Answer 1

No.9. 1:800=1×800.
800×5=4000
800×10=8000
=4000×80000=320.000.000cm²
=320.000.000:10.000
=32.000m² =d.

No.10. 50m×50m dijadikan cm.
=(50m×100)×(50m×100)
=5000cm×5000cm
=5000cm÷200 × 5000cm÷200
=25cm×25cm(menurut hitungan saya,jawabannya 25cm×25cm)

maaf kalo salah...semoga membantu
