Answer 2

Let the side of the square be ' a ' and diagonal of length ' d ' .

Given :

square of the diagonal ,

⇒ d² = 128 cm²

⇒ d = √128 = √(8² x 2) = 8√2 cm

we know in a square, length of the diagonal,

d = √2 x a

⇒ a = d / √2

⇒ a = (8√2) / √2

 ∴ a = 8 cm

Therefore the length of the required square is 8 cm .
