Question

The length and breadth of the rectangle are ( 3 x - 1 ) and ( 2 x - 5 ) units respectively. If it is a square, then find the value of k.

Answer 1

I think you want to ask the value of x.
in square length and breadth are equal,do equate these
3x-1=2x-5
3x-2x=-5+1
x=-4
because length can not be -ve quantity,so take the absolute value.
x=4
