Question

The area of a square is 450 sq. cm, the length of a diagonal is

1. 30 cm
2. 38 cm
3. 25 cm
4. 32 cm ​

Answer 1

==> $\sqrt{450} =$ side of square

==>21.21cm

diagonal is root 2 bigger than sider so....................

$\sqrt{2}=1.41 approx$

 ==> lenght of diagonal  ==> 21.21+1.41

==> 22.61 (approxx)

so, 3 is correct beacuse some approximaty is there.............

ur answer is 25..............

Answer 2

==> \sqrt{450} =

450
