\(14{\rm{da}}{{\rm{m}}^2} = 14 \times 100{\rm{ }}{{\rm{m}}^2} = 1400{{\rm{m}}^2}\)

\(1700{{\rm{m}}^2} = 1700:100{\rm{ da}}{{\rm{m}}^2} = 17{\rm{da}}{{\rm{m}}^2}\)

\(16{\rm{da}}{{\rm{m}}^2}10{{\rm{m}}^2} = 16{\rm{da}}{{\rm{m}}^2} + 10{{\rm{m}}^2} = 16 \times 100{{\rm{m}}^2} + 10{{\rm{m}}^2} = 1610{{\rm{m}}^2}\)

\(37{\rm{da}}{{\rm{m}}^2}9{{\rm{m}}^2} = 37{\rm{da}}{{\rm{m}}^2} + 9{{\rm{m}}^2} = 37 \times 100{{\rm{m}}^2} + 9{{\rm{m}}^2} = 3709{{\rm{m}}^2}\)

\(1{{\rm{m}}^2} = 1:100{\rm{ da}}{{\rm{m}}^2} = \frac{1}{{100}}{\rm{ da}}{{\rm{m}}^2}({\rm{hay }}0,01{\rm{da}}{{\rm{m}}^2})\)

\(8{\rm{da}}{{\rm{m}}^2} = 8:100{\rm{h}}{{\rm{m}}^2} = \frac{8}{{100}}{\rm{h}}{{\rm{m}}^2}({\rm{hay }}0,08{\rm{h}}{{\rm{m}}^2})\)

\(26{{\rm{m}}^2} = 26:100{\rm{da}}{{\rm{m}}^2} = \frac{{26}}{{100}}{\rm{da}}{{\rm{m}}^2}({\rm{hay }}0,26{\rm{da}}{{\rm{m}}^2})\)

\(42{\rm{da}}{{\rm{m}}^2} = 42:100{\rm{h}}{{\rm{m}}^2} = \frac{{42}}{{100}}{\rm{ h}}{{\rm{m}}^2}({\rm{hay }}0,42{\rm{h}}{{\rm{m}}^2})\)

\(15{{\rm{m}}^2} = 15 \times 10000{\rm{c}}{{\rm{m}}^2} = 150000{\rm{ c}}{{\rm{m}}^2}\)

\(7{\rm{da}}{{\rm{m}}^2} = 7 \times 10000{\rm{d}}{{\rm{m}}^2} = 70000{\rm{d}}{{\rm{m}}^2}\).
