If a, c, b are in GP, then the area of the triangle formed by the lines a x+b y+c=0 with the coordinates axes is equal to
Options
- A1
- B2
- C1 2
- DNone of these
Correct answer
C. 1 2
Step-by-step solution
Given a, c, b are in GP c^2=a b ...(i) According to question, aligned Area of O A B & = | 1 2 O A O B | = & | 1 2 ( -c b ) ( -c a ) | & = 1 2 c^2 a b = 1 2 [by Eq. (i)] aligned
