What is the Land acre formula when the plot has different lengths and widths?

What's the difference between A pilot and an Acre.

Formula for area is length x width. If you have an area that is not square or rectangular then break it into those and add the areas together. The area for a triangle is different but you should be able to find that doing a search for "formula for triangle area".

Once you have the area then then you can figure how many acres. An acre is 43,560 square feet or 4,840 square yards - if you need metric just convert as usual.

For example: If your plot has 6 sides of 100', 15', 37', 10', 63', and 25' (an L shape) you can do 15x100 + 10x63 = area or 37x15 + 63x25 = area ... both give you an area of 2130 square feet. 2130/43,560 = .05 acres.

Hope this helps :)
