If two sides of a square are 4 x+3 y-20=0 and 4 x+3 y+15=0 , then the area of the square is
Options
- A36 sq. units
- B16 sq. units
- C4 sq. units
- D49 sq. units
Correct answer
D. 49 sq. units
Step-by-step solution
Given equations of lines are 4 x+3 y-20=0 and 4 x+3 y+15=0 Slope of 4 x+3 y-20=0 is -4 3 . Slope of 4 x+3 y+15=0 is -4 3 Lines are parallel. Distance between two parallel lines aligned & = | c₁-c₂ a^2+b^2 | & = | -20-15 4^2+3^2 | & = 35 5 =7 units aligned Area of square =7^2=49 sq. units
