u can use application of pgt for obtuse angled triangle and u need to draw construct AD perpendicular to BC
then extend BC to intersect AD at D
Now,
(AC)^2 = AB^2 + BC^ 2 + 2 BC.BD ( by application of p.g.t).......(1)
now make use of construction and show BD = AD ....(2)
then u can use area of triangle
A ( triangle. ABC) = 1/2 BC . AD
4A ( triangle ABC) = 2 BC.AD .......(3)
now from (1) (2) and (3) u can get the answer
