Easy
mathematics can take a lot of the guess work out of measuring your
turf area. Use any of the following formulas to meet your yard
design or layout.
Circle A = 3.14 x
r2
Example: Circle's radius (r) is 10 feet.
Multiply the known 3.14 by the radius squared.
Thus: A = 3.14 x 102 A =
3.14 x 100 A = 314 square feet
Square
& Rectangle A = Base x Height
Example: Square or Rectangle's base is 10
feet, and the Square or Rectangle's height is 10 feet.
Thus: A = 10 x 10 A = 100 square
feet
Triangle A = (Base x
Height)÷2
Example: Triangle's base is 10 feet and the
height (base to point) is 20 feet.
Thus: A = (10 x 20)÷2 A = 200÷2 A = 100 square feet
Combination
Free-Form
Break the
free-form area down to obvious forms and calculate each form's area.
Once each form is calculated, add the areas together to derive the
total area.
Breakdown to
Forms
Example:
Circle A = 3.14 x r2
Rectangle A = b x h
Square A = b x h
(As a rule it is wise to add an additional 10% to cover
estimation and measuring error for a free form lawn)
