# Field Area

Each area calculator determines the area of rectangular, triangular, circular and trapezoidal fields.

## Rectangular Field Area

Length:
Width:
Rectangular Area:

Base:
Height:
Triangular Area:

Circle Portion:
Circular Area:

## Trapezoidal Field Area

Length 1:
Length 2:
Width:
Trapezoidal 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 (degrees)

#### 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)
