Measuring Odd Shaped Lawns

Use any of the following formulas to meet your yard design or layout. We recommend planting a minimum of one plug per square foot.

A = 3.14 x r2
Example: Circle's radius (r) is 10 feet. Multiply the constant 3.14 by the radius squared.

Area = 3.14 x 102
Area = 3.14 x 100
Area = 314 square feet

A = (b x h) ÷ 2
Example: Triangle's base (b) is 10 feet and the height (h) from base to point is 20 feet.

Area = (10 x 20) ÷ 2
Area = 200 ÷ 2
Area = 100 square feet
Combination Free-Form

Break the free-form shape down to simple forms, then calculate each form's area. Once each area is calculated, add the areas together to yield the total area.
Breakdown to Simple Shapes

  1. Circle (A = 3.14 x r2)
  2. Rectangle (A = b x h)
  3. 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.)
