Worth Knowing
Area drives how much paint, flooring, or tile you buy, while perimeter governs skirting board, coving, and trim — this tool gives both because a renovation needs each. For anything but a plain rectangle, the reliable method is to split the space into rectangles, calculate each, and add them. Measuring twice before ordering is the cheapest step in any project; a small error in one dimension multiplies straight into the area and the materials bill.
