Google Map Area Calculator-HELP

[3FLa]

I guess I am not as smart as I like to think I am. I am having trouble with Google Map Daft Logic. The site was recommended on SC and I thought it was great, but I must be doing something wrong in application.

Here is the issue. I own land and my neighbor wants to lease a section of his property to me. His section is 3000' in width and 2900' in length. The land deed states it is more/less 206 acres. Using the Heron's Formula, I calculate it to be 209 acres. Using the Laws of Cosines, I calculate it to be 209 acres. Using the old time Farmer's tool (L x W divided by 43560') I get 199 acres. All formulas produce a reasonable margin.

Now, when I use the area calculator from Google, I am getting less than a total area of 75 acres.

Can someone please explain what this dumb a$# cajun is doing wrong.

Thanks to all for taking time to help!
