I am looking for a acreage calculator that I can use to determine the acres
in a lot that has different lengths on each side.
ex. 70x 234.6x 180x 304.5.

Can't be done unless you know the included angles.

Their ethics are a short summary of police ordinances: for them the
most important thing is to be a useful member of the state, and to air
their opinions in the club of an evening; they have never felt the
homesickness for something unknown and far away, nor the depths which
consists in being nothing at all. ___________Soren Kierkegaard

You really think 70x 234.6x 180x 304.5 can have more than one set of
included angles ?

Sure. A triangle has one possible configuration for a given set of side lengths. Four (or more)
sided figures have many possible configurations. (Triangles are stable, four sided figures are not.)

___________________________________________________________________________

Using only two of the ininite number of angles that can be formed using
these side dimensions:


With an angle of approximately one degree between the 70 ft. side and the
234.6 ft side the acreage comes out to be.3928609 Acres more or less.

With an angle of approximately 126 degrees between the 70 ft. side and the
234.6 ft side the acreage comes out to be .7317 Acres more or less


The more or less is commonly used in deeds and abstracts because the
measurement are not precise.

I drew these out in Intellicad and worked out the information using that
program.

Thanks for the info.
 
You should be able to find a free CAD or Mapping program to draw your
shape - this will then give you the area.

Looks like you aren't paying attention. Your suggestion will only work
if he knows at least one/more of the angles. Simply knowing the length
of the four sides will not be enough to get the area. As has already
been clearly explained.

Regards, John.

Anyone here get their Higher School Certificate (or non-Australian
equivalent?) Draw a line the scaled length of the longest side. Using a
compass, draw arcs from the endpoints for the 2nd longest and shortest
lengths. With a ruler or pair of dividers, find two points on those arcs
that are the scaled distance of the remaining sides apart. This gives a
diagram of one of an infinite number of solutions. Construct a sqaure with
sides the length of the shortest side and place it flush against that
shortest side. Extend the opposite side of the box. You have now converted
your shape - ALL of the possible shapes - into 3 triangles and 1 box, all of
which have the length of at least one side defined, some with two, and a
second side in common with something else. Solve these as simultanious trig
equations until you have the lengths of 2 sides defined for all 3 triangles.
Area of a triangle is half length times height, so the area of the resulting
shape, regardless of which unique solution has been found for the overall
shape, is the sum of the areas of the square and the three triangles.

Thanks for the info. Do you have any suggestions?
