The area enclosed by the pair of lines x y=0 , the line x-4=0 and y+5=0 is

Options

  1. A10 sq units
  2. B20 sq units
  3. C0 sq units
  4. D5 4 sq units

Correct answer

B. 20 sq units

Step-by-step solution

We have, aligned & x y &=0, x-4=0, y+5=0 & x &=0, y=0, x=4, y=-5 aligned So, arca enclosed = Area of rectangle O A B C=A B B C=5 4 = 20 sq units
