Figure Out Lot Acreage

Grazing land can be measured in acres.


When you are selling or buying land, you want to know exactly how much land is involved so you can price the land appropriately. When looking for larger lots, acres is a common unit of measure to figure the lot area. Knowing the area helps buyers have a better idea of how they can use the land.


Instructions


1. Subdivide the lot into smaller sections of squares, rectangles, triangles and circles, if necessary. For example, subdivide a trapezoid-shaped lot into a rectangle and two triangles.


2. Measure the dimensions of the lot. For smaller lots, you may be able to use a long tape measure. For larger lots, you may need to use a click wheel to measure the dimensions.


3. Calculate the area, in square yards, of each subsection of the lot using the standard area formula for that shape. (If you did not need to subdivide, skip to Step 5.) For squares, multiply the length of a side by itself. For triangles, multiply the base times the height then divide by 2. For rectangles, multiply the length times the width. For circles, divide the diameter by two, square the result and multiply by 3.14. For example, if you had a triangular plot with a base of 400 yards and height of 200 yards, you would multiply 400 by 200, then divide by 2 to get 40,000 square yards.


4. Add the area of each subsection together to get the total area of your lot.


5. Convert from square yards to acres by dividing the square yards by 4,840. In this example, you would divide 40,000 by 4,840 to get 8.26 acres. If you measured the lot area in square feet, divide the total area by 43,560 to find the number of acres.
