Solution

The correct option is A 3x4y+11=0,3x4y9=0,4x+3y+3=0,4x+3y17=0
Given the centre of square is A(1,1) and length of square is 4
one side of square is parallel to line 3x4y=0 hence
The equation of one side is3x4y+λ=0
The perpendicular distance from centre of square to all sides is 2
Hence ∣ ∣34+λ32+42∣ ∣=2
1+λ25=±2
1+λ=±10
λ=11 and λ=9
Hence Eq of sides 3x4y+11=0 and 3x4y9=0
Now the other two sides of square should be perpendicular
Hence equation of sides is 4x+3y+μ=0
The perpendicular distance from centre of square to all sides is 2
Hence ∣ ∣4+3+μ32+42∣ ∣=2
7+μ25=±2
7+μ=±10
μ=3 and μ=17
Hence Eq of other two sides 4x+3y+3=0 and 4x+3y17=0
