Work Out Square Meter Calculator

Length (m):
Width (m):

Here’s a table explaining how to calculate square meters for different shapes and situations:

Shape / Situation	Formula / Method	Example
Rectangle / Square	Length × Width	5m × 4m = 20m²
Triangle	(Base × Height) ÷ 2	(6m × 4m) ÷ 2 = 12m²
Circle	π × (Radius²)	3.14 × (3m × 3m) = 28.26m²
Trapezium	((Base1 + Base2) × Height) ÷ 2	((4m + 6m) × 5m) ÷ 2 = 25m²
Irregular Shape	Divide into smaller shapes, calculate individually, then sum	Varies
Wall / Floor / Ceiling	Length × Height (for walls) or Length × Width (for floors)	3m × 2.5m = 7.5m²
Cylinder (Lateral Surface)	2 × π × Radius × Height	2 × 3.14 × 2m × 5m = 62.8m²
Room Area (Multiple Walls/Floors)	Sum up the area of all walls/floors separately	Varies
Land / Plot	Use appropriate shape formula or surveyor’s measurement	Varies
