The area (in sq. units) of the triangle formed by the latus rectum and the tangents at the end points of the latus rectum of x 2 16 - y 2 9 = 1 is equal to
Correct answer
4.05
Step-by-step solution
For the given hyperbola, e = 5 4 From the figure, P S 1 = b 2 a = 9 4 Meeting point of tangents at P   &   R is Q a e , 0 ≡ 16 5 , 0 Hence, the area of the triangle, A = 1 2 ⋅ 9 2 ⋅ 9 5 = 4.05 sq. units
