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
