How to calculate the area of a square
Sod Calculator Square
  • Measure the length and the width of your area in feet.
  • Multiply the two numbers together.
  • Total is the square footage required.

Example: 25’ x 25’ = 625 sq. ft.

How to calculate the area of a rectangle
Sod Calculator Rectangle
  • Measure the length and the width of your area in feet.
  • Multiply the two numbers together.
  • Total is the square footage required.

Example: 40 ’ x 15 ’ = 600 sq. ft.

How to calculate the area of a circle
Sod Calculator Rectangle
  • To calculate the sq. ft. of a circle, multiply the radius by the radius, then multiply by 3.14.
  • The radius is half the distance across the circle.

Example: 20’ x 20’ = 400 x 3.14 = 1,256 sq. ft.

How to calculate the area of a triangle
  • To figure the area of a triangle, multiply the base by the height and divide by 2

Example: 10’ x 10’ = 100 ’ ÷ 2 = 50 sq. ft.

How to calculate the area of a trapezoid
A trapezoid is a 4 sided figure with one pair of parallel sides.

To find the area of a trapezoid,
  • Measure the length of each parallel side in feet.
  • Add the lengths together.
  • Multiply the result by the height.
  • Divide the result by 2

Example: 20’ + 10’ x 15’ ÷ 2 = 225 sq. ft.

How to calculate the area of a parallelogram
  • A parallelogram is a 4sided shape formed by two pairs of parallel lines.
  • Opposite sides are equal in length and opposite angles are equal in measure.
  • To find the area of a parallelogram, multiply the base by the height.

Example: 25’ x 15’ = 375 sq. ft.

How to calculate the area of an odd shaped oval
  • For example, a golf practice tee with bell shaped ends actually looks as if it is an irregular shape. However, it can be easily divided into a number of regular shapes—a rectangle and two half circles.
  • Therefore the formulas for the area of a rectangle and area of a circle can be used to calculate the area.

Example: (40' x 20' = 800 sq. ft.) + (10' x 10' x 3.14 = 314) = 1,114 sq. ft.

How to calculate the area of an odd shaped area
    • Any area bounded by more than 4 sides may be divided into a series of triangles by diagonal lines and the area of each computed by multiplying the base times the height, and dividing by 2.
    • The sum of the triangles is the total square footage required.

Example:
      (10' x 8’ = 80) + (20’ x 7’ = 140) ÷ 2 = 110 sq. ft.
