Question

3. Find the side of a square whose diagonal is 10v2 cm.
(a) 572 cm (b) 1072 cm (c) 5 cm
(d) 10 cm​

Answer 1

Answer:

Length of the diagonal =16

2 cm

Let the side of the square =s

Then,

s 2 +s 2 =(16 2 ) 2

2s 2 =16×16×2

s=16cm

Side of the square = 16 cm

Answer 2

Answer:

Let the side of the square = a

Diagonal ( d ) = 10√2

=> √2 a = 10√2

=> a = 10√2/√2

a = 10 cm ---( 1 )

Perimeter = 4a

P = 4 × 10

P = 40 cm

Therefore ,
