Question

Số?

a) 1 m² = ? dm² = ? cm²                      1 cm² = ? mm²

1 dm² = ? cm² = ? mm²                       1 m² = ? mm²

b) 6 200 dm² = ? m²                           247 dm² = ? m² ? dm²

3 600 mm² = ? cm²                           360 mm² = ? cm² ? mm²

54 000 cm² = ? dm²                          1 580 cm² = ? dm² ? cm²

150 000 cm² = ? m²                          5 604 dm² = ? m² ? dm²

Answer 1

a) \(1m^2=100dm^2=10000cm^2\)

\(1dm^2=100cm^2=10000mm^2\)

\(1cm^2=100mm^2\)

\(1m^2=1000000mm^2\)

b) \(6200dm^2=62m^2\)

\(3600mm^2=36cm^2\)

\(54000cm^2=540dm^2\)

\(150000cm^2=1500m^2\)

\(247dm^2=2m^247dm^2\)

\(360mm^2=2cm^260mm^2\)

\(1580cm^2=15dm^280cm^2\)

\(5604dm^2=56m^24dm^2\)
