tolong jawab ya semuanya pake cara

No.1= 12 m × 9 m= 108 M (persegi)
= 108 m2 jadikan cm2
= 108×10.000= 1.080.000 cm
= 1.080.000 ÷ (30×30)
= 1.080.000 ÷ 900 = 1200
= 1.200 keramik

No.2= Keliling tanah = 45+45+45+45
= 90+90 = 180 m
= 180 ÷ 15 = 12 pohon

No.3 = 60× 45 = 2.700 m2
= 3/4 × 2.700 = 2.025 m2 (ditanam)
.... padi
= untuk tambak= 2.700 - 2.025 =
= 675

No.4 = 10 × 3,5 = 10 × 35 ÷ 10 = 35 M2
= 35 M2 + 35M2
= 70 M2

No.5 = 3 km×6m(jadikan m)
. = (3×100.000)×6
= 300.000-3 =
= 297.000 (yg tak di aspal
= luas yg tak diaspal= 297.000×6
.. = 1.780.000M2

kalo versiku bgini ya jwbanx...semoga benar
