Transforming the width and/or height of text layer?

In Extendscript, how do I change the width and height of a text layer separately? I know about changing the font size but that is more generalized, I want specific changes in the width and/or height.

I used Scriptlistener to get some code. When the original width is 14.5 inches and height is 6 inches, then increasing one of width or height by 0.1 inches performs a horizontal or vertical offset of 3.6000 (which I assume is pixels):

var idTrnf = charIDToTypeID( "Trnf" );
var desc231 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref1 = new ActionReference();
var idLyr = charIDToTypeID( "Lyr " );
var idOrdn = charIDToTypeID( "Ordn" );
var idTrgt = charIDToTypeID( "Trgt" );
ref1.putEnumerated( idLyr, idOrdn, idTrgt );
desc231.putReference( idnull, ref1 );
var idFTcs = charIDToTypeID( "FTcs" );
var idQCSt = charIDToTypeID( "QCSt" );
var idQcsa = charIDToTypeID( "Qcsa" );
desc231.putEnumerated( idFTcs, idQCSt, idQcsa );
var idOfst = charIDToTypeID( "Ofst" );
var desc232 = new ActionDescriptor();
var idHrzn = charIDToTypeID( "Hrzn" );
var idRlt = charIDToTypeID( "#Rlt" );
desc232.putUnitDouble( idHrzn, idRlt, 3.600000 );
var idVrtc = charIDToTypeID( "Vrtc" );
var idRlt = charIDToTypeID( "#Rlt" );
desc232.putUnitDouble( idVrtc, idRlt, 0.000000 );
var idOfst = charIDToTypeID( "Ofst" );
desc231.putObject( idOfst, idOfst, desc232 );
var idWdth = charIDToTypeID( "Wdth" );
var idPrc = charIDToTypeID( "#Prc" );
desc231.putUnitDouble( idWdth, idPrc, 100.689655 );
var idIntr = charIDToTypeID( "Intr" );
var idIntp = charIDToTypeID( "Intp" );
var idBcbc = charIDToTypeID( "Bcbc" );
desc231.putEnumerated( idIntr, idIntp, idBcbc );
executeAction( idTrnf, desc231, DialogModes.NO );

I do not know how this 3.6000 is being calculated. Maybe if I find out about the logic behind this, then I can write some code
