Answer 2

$area \: of \: square = {a}^{2} \\ so \: 100 = {a}^{2} \\ \: \: \: \: \: \: a = \sqrt{100} \\ \: \: \: \: \: \: a = 10$

$perimeter \: of \: square = 4a \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 4 \times 10 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 40(ans)$
