consider d fig u get......
d slope of oppposite sides wud be same...............ryt!
n slope of adjacent sides wud be negative reciprocal of each oder
dat means d point at which tangent r made r
if parameter of a point is '@"
den
four pts r
(3cos @,2 sin @)
(-sec @/3, cosec @/2)
(-cos @/3,-sin @/2)
(sec @/3, -cosec @/2)
so
now get d intersection points .....
here apply d condition dat allsides r equal
this gives value of @
now calculate area by side^2

nobody is wrong
even a stopped clock is right twice a day |
