__Area Calculations__: Draw your site as accurately as possible - graph paper works well. For odd or complex shapes, divide the area into combinations of rectangles, triangles, and/or circles. Use the following formulas to determine area:

**Rectangle: Area = length x width**

**Circle: Area = 3.1416 x the square of the radius**

**Triangle: Area = 1/2 x length of base x length of height**

**To determine topsoil requirements for areas of varying grade, use a transit to indicate exact fill requirements...or estimate an average fill depth. **
