What is the area of triangular region ABC above?

What is the area of triangular region ABC above?

(1) The product of BD and AC is 20.
(2) x = 45

Statement 1:

 The product of BD and AC is 20.

i.e. BD*AC = 20

Area of a triangle = 1/2 * base * height = 1/2 * BD*AC = 1/2*20 = 10

Sufficient

 

Statement 2:

 x = 45

No information about the size of the triangle is given, hence insufficient.
