What would be the best way to scale this shape (property outline with housing units) to real size?

So I’m trying to scale this whole image to the dimensions of real life. I tried using a measurement from the parcel map that this img is based on, but when I scale one line of the perimeter, it just scales that.

Thank you!

Make the parcel a group. Open the group for editing. Use the Tape Measure tool to measure a border. Type the real length of the border. Click OK to the dialog box that appears.


Perfect. thank you
