Calculating the Sq. Ft. area of an uneven lot

[Eli Weiss]

Here is the survey of the subject lot, its 20X105 and the front and 57X105 at the rear, I was googling for the correct calculator and came across this one, is this the right one to use? I am getting a total of 4,042 Sq. Ft.

The other way I did is 20X105 =2,100 57X105= 5985 +2,100 =8,085 ÷2 =4,042

= -((37*105)/2)+(57*105)

= 4,042.5

Round up (or down...close enough)

 

[DMZwerg]

= -((37*105)/2)+(57*105)

= 4,042.5

Round up (or down...close enough)

As long as the standard corners are right angles, yes.
Would be a little different if they are not so calling it estimated 4042sf would be most correct IMHO.

How does one become a Certified Residential Appraiser without a knowledge of basic geometry?

This isn't even a weird shaped site.

As long as you have two parallel sides....

It's still basic geometry. Easy unless you have one with rounded corners. It can still be done geometrically but can be time consuming. Luckily, the tax records for my market area show the square footage of lots. That is good enough for guv'ment work, as far as I'm concerned.
