Question

24.7 dm^2 =_______ cm^2=______m^2

Answer 1

`24.7 \mathrm{dm}^(2)=2470 \mathrm{cm}^(2)=0.247 \mathrm{m}^(2)`

Solution:

Given that , 24.7 dm ^ 2 = _______ cm ^ 2 = ______ m ^ 2

We have to find the equivalent of
`24.7 \mathrm{dm}^(2) \text { in } \mathrm{cm}^(2) \text { and } \mathrm{m}^(2)`

`\text { First let us find } 24.7 \mathrm{dm}^(2) \text { equivalent in } \mathrm{cm}^(2)`

we know that, 1 decimeter ( dm ) = 10 centimeters ( cm )

`\text { So, } 24.7 \mathrm{dm}^(2)=24.7 *(10 \mathrm{cm})^(2)=24.7 * 100 \mathrm{cm}^(2)=2470 \mathrm{cm}^(2)`

`\text { Now, let us find } 24.7 \mathrm{dm}^(2) \text { equivalent in } \mathrm{m}^(2)`

We know that, 1 decimeter ( dm ) = 0.1 meter ( m )

`\begin{array}{l}{\text { So, } 24.7 \mathrm{dm}^(2)=24.7 *(0.1 \mathrm{m})^(2)=24.7 * 0.01 \mathrm{m}^(2)=0.247 \mathrm{m}^(2)} \\\\ {\text { Hence, } 24.7 \mathrm{dm}^(2)=2470 \mathrm{cm}^(2)=0.247 \mathrm{m}^(2)}\end{array}`
