Example: 5’ x 10’ x 3.14 = 157 sq. ft.

Trapezoid Lawn Measure — Ellicott, CO — Schubert’s Sod Depot

How to calculate the area of a trapezoid

  • A trapezoid is a 4 sided figure with one pair of parallel sides.
  • Measure the length of each parallel side (Base A & B) in feet.
  • Add the lengths together.
  • Multiply the result by the height.
  • Divide the result by 2


Example: 15’ + 25’= 40 x 10’= 400 ÷ 2 = 200 sq. ft.

Parallelogram Lawn Measure — Ellicott, CO — Schubert’s Sod Depot

Odd Shaped Lawn Measure — Ellicott, CO — Schubert’s Sod Depot

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 shapes making it easier to calculate.
  • The sum of the shapes is the square footage needed.


Example:

Shape A : 10’ x 10’ = 100 sq.ft.

Shape B : 10’ x 15’ = 150 ÷ 2 = 75 sq.ft.

Sum of the shapes : 100’ + 75’ = 175 sq.ft.
