The area of the region enclosed between pair of line x y = 0 and the lines x y + 5 x - 4 y - 20 = 0 is …..
Options
- A20 square units
- B4 5 square units
- C10 square units
- D6 square units
Correct answer
A. 20 square units
Step-by-step solution
Given pair of lines x y + 5 x - 4 y - 20 = 0 ⇒ x y + 5 - 4 y + 5 = 0 ⇒ y + 5 x - 4 = 0 ⇒ x = 4 , y = - 5 and also, x y = 0 ⇒ x = 0 , y = 0 Now, draw the graph of the pairs of line ∴ Required area of bounded region = 4 × 5 = 20 s q . u n i t s
