If $a, c, b$ are in G.P., then the area of the triangle formed by the lines $a x + b y + c = 0$ with the coordinates axes is equal to

Options:

Answer:

Solution:

Area of the triangle $= \frac{1}{2} (x$ intercept $) \times (y$ intercept $)$ $= \frac{1}{2} (- \frac{c}{a}) (- \frac{c}{b}) = \frac{1}{2} \frac{c ^{2}}{ab} = \frac{1}{2} unit$ $[∵ a, c, b$ are in $G . P . \Rightarrow c^{2} = ab]$
