Answer 2

Answer:

$\red { square \: of \:42 }\green { = 1764}$

Step-by-step explanation:

$\red { square \: of \:42 }$

$= 42^{2}\\=(40+2)^{2}$

$= 40^{2} + 2\times 40 \times 2 + 2^{2}$

$\boxed { \pink { (a+b)^{2} = a^{2}+2\times a\times b + b^{2}}}$

$= 1600 + 160 + 4$

$\green { = 1764}$

Therefore.,

$\red { square \: of \:42 }\green { = 1764}$
