Question

Which of the following is the square of 38?

• A. $1,444$
• B. $1,024$
• C. $1,296$
• D. $1,369$

Answer 1

The correct option is A $1,444$

$\text{Method I}$
We have to find the square of 38. So,
${38}^2=38\times 38=1,444$
$\text{Method II}$
First subtract $25$ from $38$
$38-25=13$
Now, $50$ is 12 more than 38 so,
Add ${12}^2$ to $13\times 100=1300$
$⟹1,300+144=1,444$
So, $1,444$ is the square of $38$
