In the circle given below, let OA = 1 unit, OB = 13 unit and PQ $\perp$ OB. Then, the area of the triangle PQB (in square units) is

Correct Option - 1


Detailed Solution:

By properties,

OA.AB = PA.AQ, OA=1, AB = 12

12 = a²

$a=2\sqrt[]{3}$

$\therefore AreaofPQB=\frac{1}{2}\times 12\times 2.2\sqrt[]{3}=24\sqrt[]{3}$ sq. units
