उत्तर

The given parallel lines can be written as
4x + 3y − 11 = 0            ... (1)

\[4x + 3y - \frac{15}{2} = 0\]     ... (2)
Let d be the distance between the given lines.
\[\Rightarrow d = \left| \frac{- 11 + \frac{15}{2}}{\sqrt{4^2 + 3^2}} \right| = \frac{7}{2 \times 5} = \frac{7}{10}\] units
