The perimeter of ( A B C ) is (36 ~cm ) and its in radius is (8 ~cm ). Then, the area of the triangle is

Options

  1. A(144 ~cm ^2 )
  2. B(124 ~cm ^2 )
  3. C(164 ~cm ^2 )
  4. D(104 ~cm ^2 )

Correct answer

A. (144 ~cm ^2 )

Step-by-step solution

In radius ((r)= S ) ( aligned & =(r s), Area, S Semi-perimeter & =8 36 2 =144 ~cm ^2 aligned )
