__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. Usually soil does not have to be ordered all at
once so you can always bring in more...better too little than
too much! **
