When dealing with properties of irregular shapes, what must you do before calculations?

When dealing with properties of irregular shapes, dividing the area into rectangular parcels is a critical first step before calculations. This method allows for the simplification of the calculation process. Since irregular shapes do not have straightforward formulas for calculating area, breaking them down into more manageable rectangles enables appraisers to apply the standard area formula (length x width) to each rectangular section.

This segmentation facilitates accurate measurements and adds clarity to the analysis. Once the rectangular areas are calculated, the areas can then be summed to determine the total area of the irregular property. The use of this systematic approach is fundamental in achieving reliable appraisal outcomes, making it a standard procedural method in such assessments.
