Question

show me step by step 16. 38 CM square divide by 15.6 CM

Answer 1

$\dfrac{(16.38) {}^{2} }{15.6}$



First solving the numerator which is ( 16.38 )²

= > ( 16.38 )²

= > ( 16.38 ) × ( 16.38 )

$= > \dfrac{16.38}{1} \times \dfrac{16.38}{1}$



Divide by 100 on numerator and denominator


$= > \dfrac{16.38 \times 100}{1 \times 100} \times \dfrac{16.38 \times 100}{1 \times 100}$


$= > \dfrac{1638}{100} \times \dfrac{1638}{100}$


$= > \dfrac{1638 \times 1638}{100 \times 100}$




Then, solving denominator which is 15.6


= > 15.6

$= > \dfrac{15.6}{1}$


Multiply by ( 100 × 100 ) on numerator and denominator both


$= > \dfrac{15.6 \times 100 \times 100}{1 \times 100 \times 100}$


$= > \dfrac{156 \times 10 \times 100}{100 \times 100}$





So,


$= > \dfrac{(16.38) {}^{2} }{15.6} \\ \\ \\ = > \dfrac{ \dfrac{1638 \times 1638}{100 \times 100} }{ \dfrac{156 \times 10 \times 100}{100 \times 100} }$



Removing ( 100 × 100 )


$= > \dfrac{1638 \times 1638}{156 \times 10 \times 100} \\ \\ \\ \\ = > \frac{10.5 \times 1638}{10 \times 100} \\ \\ \\ \\ = > \frac{ 1.05 \times 1638}{100} \\ \\ \\ \\ = > 0.0105 \times 1638 \\ \\ \\ = > 17.199$




As the question is in cm.

On dividing cm² by cm, we will get cm.



So,

After dividing we get 17.199 cm.
