Hi Neha ...
it is answered before ! :)

Neways !!

we knwo this is a similar traingles !!

so one rule to remember is !!

in a similar triangle !

squares of ratios of the two sides = ratio of the area !

in other words

AB^2/ab^2=2/1

S^2/s^2=2/1

Therefore S=root2 *s

Vishu
KILL !! DIE !! or BEAT my FEAR !!! de@D END!!

Hey vishubn,

Thanks a lot.. I did not find this problem when I put a search...

I knew this was a similar triangle concept but somehow missed on applying the concept.. Thanks again...
