Question

find the length of a diagonal of a spuare of side 6 cm​

Answer 1

Answer:

Diagonal of sq . = √6^2 + 6^2

= √36+36

= √72

=√2×2×3×3×2

= 2×3×√2

= 6 √2 cm Ans...

Answer 2

Answer:

the side of the square is 6 centimetre now the diagonal will made it right angle triangle so we can use Pythagoras to find the length of diagonal.

Step-by-step explanation:

let let ABC be any triangle in right angle triangle the length of diagonal is bc and the sides are AB and AC

BY PYTHAGORAS

${bc}^{2} = {ac}^{2} + {ab}^{2}$

$bc = \sqrt{ {6 }^{2} + {6}^{2} } = \sqrt{36 + 36} = \sqrt{72}$
