## How to calculate square meters?

Calculating the area in square meters of different geometric shapes, such as a square, rectangle, or triangle, is a skill that can assist you in many everyday situations. Below is a simple explanation of how to do it, along with examples of situations where these calculations can be useful.

### Square:

If you want to calculate the area of a square, you only need the length of one side. The formula for the area of a square is:

```Area = side x side
```

Suppose you want to calculate the area of a square plot of land that you want to plant with flowers. The side is 5 meters. The calculation then becomes:

```Area = 5 m x 5 m = 25 m²
```

### Rectangle:

For a rectangle, you need the length and width of the rectangle. The formula for the area of a rectangle is:

```Area = length x width
```

Imagine you want to lay a new floor in your living room that is 6 meters long and 4 meters wide. The calculation then becomes:

```Area = 6 m x 4 m = 24 m²
```

This means you need 24 square meters of flooring.

### Triangle:

For a triangle, you need to know the base and height. The formula for the area of a triangle is:

```Area = 1/2 x base x height
```

Suppose you want to make a triangular sail for your boat. The base of the triangle is 4 meters and the height is 3 meters. The calculation then becomes:

```Area = 1/2 x 4 m x 3 m = 6 m²
```

This means you need 6 square meters of fabric to make your sail.

Knowing these simple formulas can help you plan all sorts of projects, from gardening to interior decoration and much more.
