25 dm2 = 25 : 100 = \(\dfrac{1}{4}\) m2
36 dm2 = 36 : 100 = \(\dfrac{9}{25}\) m2
450 cm2 = 450 : 10000 = \(\dfrac{9}{200}\) m2
575 cm2 = 575 : 10000 = \(\dfrac{23}{400}\) m2
\(25dm^2=\dfrac{25}{100}m^2=\dfrac{1}{4}m^2\)
\(36dm^2=\dfrac{36}{100}m^2=\dfrac{9}{25}m^2\)
\(450cm^2=\dfrac{450}{10000}m^2=\dfrac{9}{500}m^2\)
\(575cm^2=\dfrac{575}{10000}m^2=\dfrac{23}{400}m^2\)
25 dm2 = 25 : 100 = \(\dfrac{1}{4}\) m2
Mình sửa lại nhé! Tại công thức lỗi.
