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
