Mathematics

$\boxed{ \bold{ \huge{ \boxed{ \sf{9.69 \: cm}}}}}$

Step-by-step explanation:

Area of a square ( A ) = 94 cm²

Length of a square ( L ) = ?

Finding the length of a square

$\boxed{ \sf{area \: of \: a \: square = {l}^{2} }}$

$\longrightarrow{ \sf{94 = {l}^{2} }}$

$\longrightarrow{ \sf{ {l}^{2} = 94}}$

$\longrightarrow{ \sf{ \sqrt{ {l}^{2} } = \sqrt{94}}}$

$\longrightarrow{ \sf{l = 9.69 \: cm}}$

Hope I helped!

Best regards! :D
