Easy mathematics can take a lot of the guesswork out of measuring your turf area. Use any of the following formulas to meet your yard design or layout or use the calculator at the bottom of this page.

#### AREA IS A CIRCLE A = 3.14 x r2
Example: Circle’s radius (r) is 10 feet. Multiply the known 3.14

Thus:
A = 3.14 x 102
A = 3.14 x 100
A = 314 square feet

#### AREA IS A SQUARE OR RECTANGLE A = Base x Height
Example: Square’s or rectangle’s base is 10 feet and the square’s or rectangle’s height is 10 feet.

Thus:
A = 10 x 10
A = 100 square feet

#### AREA IS A RIGHT 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

#### AREA IS A COMBINATION FREEFORM  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.

Thus:
Circle (1) A = 3.14 x r2
Rectangle (2) A = b x h
Square (3) A = b x h
