re: Calculate total square footage for irregular lot?

assuming the back lines are 90°.
Air551 I made a great living testifying in court for my client because other surveyors, realtors and property owners of the adjacent property assumed certain things about about their boundary lines that I could disprove.

Get a VERY accurate weight scale and measure weight of the the entire drawing.
Cut out the lot, and weigh the paper for just that.
Use the scale to figure the area of the entire page and then do the lot area by ratio of the weights.

Finally, someone chimes in that actually knows what they’re talking about

Good for you sir. That's a mighty tall horse you're riding. However, he isn't representing this map as a boundary survey. Not to mention it's only a picture and doesnt show the entire sheet. You come off as quite the smartass, very unnecessarily.
Now if OP says this is a sealed boundary survey and the whole picture is represented, then yes, I have a gripe with it. And no, assumptions cant be made about bearings or basis of bearings. It's either there or not.
This clearly looks like a dumbed down snippet of the actual subdivision plat that some "Cad jockey" used to show him the layout of his house plans on the lot.
All he wanted to know is the square footage of the lot...so yes, to calculate an area from what he's been given. Assumptions have to be made. He's not asking boundary advice...

If it is drawn to scale, you can get an true acre area in autocad by tracing over the lines and scaling to a known distance provided in the survey.
No angles needed.

That actually would work!

Our county's parcel map webpage has a "Distance" tool and an "area" tool that you can click on the outline of any property at all the corners to determine the said area or lengths of each segment. For the arc in the front of the OPs lot, you would need to click on several points along the arc to get a good reading. This will only, however, get you pretty close to the lot size. I'm not sure how accurate you want it, but I'd say from the measurements that I take using the website's tool , I can get within 1% or so.

Could work, but not with this specific picture because of the angle the picture was taken at. If he scanned it or took a perfect ortho picture then yes, I could rotate and scale in CAD.

You want to borrow my digitizer? I haven't digitized a hardcopy in years. Easier to scan the drawing and import the jpg into AutoCAD.

There's an equation for that!

I just went to the legal description of the lot since since I know where this is located
Then went to the semi circle of the cul de sac thing and let Google estimate.

Digitizer? Just use a planimeter at that point.

I think I did the landscaping on your house a decade or so ago. I know I did a lot in that neighborhood at that time.

If you have that in PDF you can download Bluebeam.
You can set a scale and use the area tool to get a pretty darn accurate square footage.

We have done a lot of work since then and love the neighborhood and our neighbors. Everyone truly looks out for one another.

Yes, if there is some measurements on the plan.
