Question

If the length of diagonal of a square is 13 cm. find the length its side​

Answer 1

We know,

length of side = side of square ÷ √2

13 / √2

Answer 2

Answer:

kindly see the answer below....

Step-by-step explanation:

We know that,

the side of a square is equal...

then let assume that the side of a square be

$x$

therefore,

$given \: that \: diagonal = 13 \: cm$

so,

${side}^{2} + {side}^{2} = {diagonal}^{2}$

$or \: {x}^{2} + {x}^{2} = {13}^{2}$

$or \: 2 {x}^{2} = 169$

$or \: {x}^{2} = 84.5$

$or \: x = \sqrt{84.5} = 9.2 \: cm$

so, the length of the side of the square is 9.2 cm(approx.)...

thanks a lot....
