-
Rectangular Areas
Calculating the area of rectangular spaces involves multiplying length by width. An example is a 20-foot long by 10-foot wide garden bed, resulting in an area of 200 square feet. This figure is then input into the tool to determine the necessary tonnage of stone.
-
Circular Areas
Calculating the area of circular spaces involves using the formula r, where r represents the radius (half the diameter). For a circular patio with a 10-foot diameter (5-foot radius), the area is approximately 78.5 square feet. This number is then applied within the calculator.
-
Irregular Areas
Irregularly shaped areas often require segmentation into simpler geometric forms, such as rectangles, triangles, or circles. The areas of these individual shapes are then summed to provide an approximate total area. This approach allows for a reasonably accurate assessment of material needs for complex landscapes. Using a CAD tool can facilitate this process.
-
Impact on Material Calculation
Inaccurate area measurements lead to incorrect stone tonnage estimations. Overestimation results in excess material purchases and increased costs, while underestimation necessitates additional orders, causing delays and potential color variations in subsequent material deliveries.
