Answer 1

where are u stuck ? what u tried ?

Answer 2

I got the answer root(2)-2 ?

Answer 3

oh let me calculate and check.....

Answer 4

Ok thanks :)

Answer 5

is this your equation :
s^2-2root2 s -2 = 0

Answer 6

S^2-2roor2s+2=0

Answer 7

root*

Answer 8

i get root 2 +2

Answer 9

how did u get -2 ?

Answer 10

I just really dont know this gap year has made my mind rusty :( Let me check again and tell you :)

Answer 11

just get the equation right
S^2-2roor2s+2=0 is incorrect

Answer 12

s^2-2root2 s -2 = 0

Answer 13

Thanks Alot. :)

Answer 14

oh, welcome.
but did u get your error ?

Answer 15

Well a little explanation would help ?

Answer 16

sure, area of a square is two more than twice the length of its diagonal
means if we add 2 to
'twice the length of its diagonal'
then we can equate
area of square and 'twice the length of its diagonal'
so we get
s^2 = 2root 2 s \(\huge +2\)

Answer 17

got that ? ^

Answer 18

Thank you very much :)

Answer 19

welcome ^_^
