Question

Find the side of square whose diagonal is 8√2cm​

Answer 1

Step-by-step explanation:

$diagonal = 8 \sqrt{2}$

area of square = 1/2*d*d

= 1/2*64*2

= 64 cm sq.

$area = {side }^{2} \\ 64 = {side }^{2} \\ side = 8$

Answer 2

Step-by-step explanation:

length of the diagonal = 8√2 cm

let the side of the square be = x

then,

x² + x² = (8√2)²

2x² = 8×8×2

x = 8
