Maths: find the side and petimeter of a square whose diagnol is 10 cm​

Answer 1

As we know,

$Diagonal \: \: \: of \: \: \: square = \sqrt{2} a = 10 \\ \\ = \sqrt{2}a = 10 \\ \\ = a = \frac{10}{ \sqrt{2} } = \frac{10}{1.41421} = 7.071 \\ \\ \\ \\ \\ perimeter \: \: of \: square = 4a \\ \\ \frac{4 \times 10}{ \sqrt{2} } = \frac{40}{ \sqrt{2} } = \frac{40}{1.41421} = 28.28434$
