How To Calculate The Acreage Of A Triangle

The acre is a measurement used to quantify large areas, often tracts of land. The word "acre" comes from old Greek and Latin words meaning "field." The more acres a lot takes up, the larger the lot. If you have a triangular lot, you need to know the base and height dimensions of the lot to figure the acreage. Knowing the correct acreage helps you to accurately price a piece of property.

Step 1

Pick one side of the triangle to use as the base and measure the length in feet. It does not matter which side of the triangle that you use.

Step 2

Measure the perpendicular distance from the base of the triangle to the top of the triangle in feet. This is the height of the triangle.

Step 3

Multiply 1/2 times the base times the height. For example, if you have a length of 350 feet and a height of 600 feet, multiply 350 by 600 by 1/2 to get 105,000 square feet.

Step 4

Divide the number of square feet by 43,560 to convert to acres. In this example, divide 105,000 square feet by 43,560 to get 2.41 acres.
