If merged cells are empty set row height to a specific value

[YingFa]

Hello, I have this code and I would like to modified so when certain merged cells are empty this are adjusted to 125 row height by default. Some of these merged cells are for example A42 to BL42. Can I please have your help on this?

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim NewRwHt As Single
    Dim cWdth As Single, MrgeWdth As Single
    Dim c As Range, cc As Range
    Dim ma As Range
    With Target
        If .MergeCells And .WrapText Then
            Set c = Target.Cells(1, 1)
            cWdth = c.ColumnWidth
            Set ma = c.MergeArea
            For Each cc In ma.Cells
                MrgeWdth = MrgeWdth + cc.ColumnWidth
            Next
            Application.ScreenUpdating = False
            ma.MergeCells = False
            c.ColumnWidth = MrgeWdth
            c.EntireRow.AutoFit
            NewRwHt = c.RowHeight
            c.ColumnWidth = cWdth
            ma.MergeCells = True
            ma.RowHeight = NewRwHt
            cWdth = 0: MrgeWdth = 0
            Application.ScreenUpdating = True
        End If
    End With
    End Sub

Thank you.
