Select the cell/macro, right click on it and choose Attributes/Attribute Editor and it will give the details . Hope this helps.

The following script will report the area of a specified cell. It can be used on standard cells, pads and hard macros. Replace "cellName" will the cell you want to report the area for. If the cell has any obstructions on the overlap layer it will sum the area of the obstructions and report that as the area. Otherwise, it reports the area based on the SIZE statement in the LEF. You can modify this script according to your requirements.

set cellName "cellName"
set cellPtr [dbGet -p head.allCells.name $cellName]
if {$cellPtr == 0x0} {
  Puts "ERROR: Cannot find a cell of name $cellName."
} else {
  if {[dbGet selected.cell.allObstructions.layer.type overlap] == 0x0} {
    #
    # If the cell does not contain an obstruction on the overlap layer
    # then calculate the area using the SIZE statement in the LEF.
    #
    set size [lindex [dbGet $cellPtr.size] 0]
    set width [lindex $size 0]
    set height [lindex $size 1]
    set area [expr $width * $height]
    Puts "Area of cell $cellName is $area."
  } else {
    #
    # Else the cell contains obstructions on the overlap layer. Combine the obstructions
    # and calculate their resulting area.
    #
    set overlapLayerObsPtr [dbGet -p2 selected.cell.allObstructions.layer.type overlap]
    set totalShape {0 0 0 0}
    foreach shape [dbGet $overlapLayerObsPtr.shapes.rect] {
      Puts "rect: $shape"
      set totalShape [dbShape $shape OR $totalShape -output rect]
    }
    set area 0
    foreach rect $totalShape {
      set area [expr $area + (([lindex $rect 2] - [lindex $rect 0]) * ([lindex $rect 3] - [lindex $rect 1]))]
    }
    Puts "Area of cell $cellName is $area based on overlap layer obstructions."
  }
}
