Tips for Calculating Area

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:

• Area of a Circle

  Multiply pi ( = 3.14) by the square of the radius. If a circle has a radius of 4, its area is 3.14*16=50.24. If you know the diameter, the radius is 1/2 of the diameter.

• Area of a Rectangle or Parallelogram

  Multiply the base times the height. If a rectangle or parallelogram has a base of length 6 inches and a height of 4 inches, its area is 6*4=24 square inches

• Area of a Triangle

  Multiply the base times one-half the height. If a triangle has a base of length 6 inches and a height of 4 inches, its area is 6*2=12 square inches

• Area of a Trapezoid

  Add the lengths of the 2 parallel sides. Divide by 2 to get the average length of the parallel sides. Multiply this by the height (distance between the parallel sides)
