Question

15m2 = dm2

3m2 42dm2=dm2

7km2 528m2=m2

102m2=cm2

Answer 1

15 m2 = 1500 dm2 

3 m2 42 dm2 = 342 dm2 

7 km2 528 m2 = 7 000 528 m2 

102 m2 = 1 020 000 cm2 

k cho mk nha mk ít điểm lắm !

Answer 2

\(15m^2=1500dm^2\)

\(3m^242dm^2=342dm^2\)

\(7km^2528m^2=700528m^2\)

\(102m^2=1020000cm^2\)

Answer 3

15m2 = 1500dm2

3m2 42dm2= 342dm2

7km2 528m2= 7000528m2

102m2= 1020000cm2

tk mik nhá bn

Answer 4

15m2=0,15 dm2

3m2 42dm2= 300dm2 + 24dm2 = 324dm2

7km2 528m2 = 7000000m2 + 528 m2 = 7000528m2

102m2=1020000cm2

Answer 5

15m2=1500dm2

3m2 42dm2=342dm2

7km2 528m2= 7000528m2

102m2= 1020000cm2

Chúc bạn làm tốt!:D
