Calculate the surface area of a rectangular, circular or triangular growing space. Save the result as a Garden Area so connected tools can reuse the same measurement instead of asking for it again.
Saving creates a Garden Area that can feed fertilizer calculations, crop locations, harvest logging and bed-level yield analysis.
A rectangle uses length × width. A circle uses π × radius², with radius equal to half the measured diameter. A triangle uses ½ × base × perpendicular height. All dimensions are entered in metres, so the result is square metres.
For an irregular bed, split it into simple shapes, calculate them separately and add the areas together. That is more accurate than forcing a curved or L-shaped bed into one oversized rectangle.
For a raised bed, measure the internal or usable growing surface when thick edging materially reduces the planted space. For a circular bed, measure the diameter across the centre. For a triangle, the height must be perpendicular to the chosen base.
If paths, permanent structures or large unplanted sections sit inside the measured outline, calculate them separately and subtract them when the difference matters to the job.
