The length of diagonal of a square is 13 √2 cmFind the length of its each side. About the author Abigail
[tex]( {13 \sqrt{2} })^{2} = {x}^{2} + {x }^{2} \\ 169 \times 2 = 2 {x}^{2} \\ \frac{169 \times 2}{2} = {x}^{2} \\ \sqrt{169} = x \\ x = 13 \: \: \\ length \: of \: each \: side \: is \: 13[/tex] Reply
