Square Meters Calculator
Calculate the area in square meters and optional cost based on the chosen shape and dimensions.
This square meters calculator allows you to calculate the area of the following shapes: Square, Rectangle, Circle, Triangle, Trapezoid, Hexagon, and Octagon.
To use it, just select the shape and enter its dimensions. You can also specify the price per 1 m2, so the tool will also calculate the estimated price.
How to calculate area in Square Meters
Square
Square area [m²] = a [m] * a [m]
Example: a = 5m
Square area = 5m * 5m
Square area = 25m²
Rectangle
Rectangle area [m²] = a [m] * b [m]
Example: a = 4m | b = 10m
Rectangle area = 4m * 10m
Rectangle area = 40m²
Circle
Circle area [m²] = 𝜋 * r²
Example: r = 7m
Circle area ≈ 3.14 * (7m)²
Circle area ≈ 3.14 * 49m²
Circle area ≈ 154m²
Triangle
Triangle area [m²] = (a + b + c) / 2
Example: a = 3m | b = 4m | c = 5m
Triangle area = (3m + 4m + 5m) / 2
Triangle area = 12m / 2
Triangle area = 6m²
Trapezoid
Trapezoid area [m²] = (a + b) / 2 * h
Example: a = 2m | b = 4m | h = 5m
Trapezoid area = (2m + 4m) / 2 * 5m
Trapezoid area = 6m / 2 * 5m
Trapezoid area = 3m * 5m
Trapezoid area = 15m²
Hexagon
Hexagon area [m²] = (3√3) / 2 * a²
Example: a = 2m
Hexagon area ≈ 5.20 / 2 * (2m)²
Hexagon area ≈ 2.6 * 4m²
Hexagon area ≈ 10.4m²
Octagon
Octagon area [m²] = 2 * a² * (1+√2)
Example: a = 4m
Octagon area = 2 * (4m)² * (1+√2)
Octagon area ≈ 32m² * (2.41)
Octagon area ≈ 77m²
