option e) none of these.
can be triangle or quadrilateral.
if triangle, by hero,s formula max. area is 2sqrt5
and a quadrilateral cannot be formed of the given sides.

what made u think that quad can’t be formed?

We can arrange them in form of a trapezium, with sides 1 and 4 in parallel and two being the perpendicular distance between them…
this gives area as 1/2* 2 * (1+4)=5…max area…correct me???

try again, are you able to make a trapezium?
October 9, 2008 at 9:44 am
Yeah..i did a mistake didn’t strike..trapezium is possible buy not with height as 2…it will be less than that…
is the max area=2 sqrt(6)???

yeah , now it is fine

Explain the answer please…

me also got stumped by this questions ..
well we can make quadilateral with sides 4,3,2,1 .. which has max area as root24

what clicked on my mind is that area is max. if all the vertices lie on a circle. so we can make a cyclic quadrilateral with the given lengths.
and area will come out to be 2*sqrt(6) .
