How to read this result
Three useful checks, kept deliberately short.
A rectangular room measuring 6 m by 4 m: Multiply length by width · Double the sum of length and width · Keep the area and perimeter units separate.
Triangle perimeter is not estimated because three side lengths are required.
Formula and assumptions
Rectangle Area = Length × Width; Square Area = Side²; Circle Area = πr²; Triangle Area = Base × Height ÷ 2For circles, the primary measurement is the radius. For triangles, enter base and perpendicular height.
Keep in mind: Measure every section and subtract openings separately for irregular real-world surfaces.
