Field Area
Each area calculator determines the area of rectangular, triangular, circular and trapezoidal fields. Learn more about the units used on this page.
Rectangular Field Area
Triangular Field Area
Circular Field Area
Trapezoidal Field Area
The Equations
These Calculators use the following formulas to determine the field area.
Rectangular Field Area
Where:
= Area of the field (sq. ft)
= Length of the field (ft)
= Width of the field (ft)
Triangular Field Area
Where:
= Area of the field (sq. ft)
= Length of the Base of the field (ft)
= Distance from the base to the top of the field at a 90° from the base (ft)
Circular Field Area
Where:
= Area of the field (sq. ft)
= 3.14159
= Radius of the field (ft)
= Portion of the circle (as degrees, %, or a decimal)
Trapezoidal Field Area
Where:
= Area of the field (sq. ft)
= Length of one side of the field (ft)
= Length of the side Parallel to (ft)
= Width of the field, or distance between and (ft)
