Best answer

The slope of x +3y = 4 is 1/3
And 6x -2y = 7 is -3
So the product of the slope is 1/3 *(-3) = -1
Hence the diagonals are perpendicular to each other.

Here the answer option can be rhombus as well as square , but in rhombus the diagonals are unequal so it is more closer option. And nothing is mentioned about diagonals.
