Here, a lone pair of electron present at the equatorial position. In SF₂Cl₂, F present at axial positions and Cl present at equatorial positions. As electronegativity of F is higher than the electronegativity of Cl, therefore the bond length of S-F is lesser than the bond length of S-Cl.

Bond length of both S-F and S-Cl bonds are same because both S-F are at axial positions and both S-Cl are at equatorial position. SF₂Cl₂ has trigonal bipyramidal shape and in this shape, lone pair preferred to placed at the equatorial position, then axial. So, the location of lone pairs in SF₂Cl₂ is the same.
