The perimeter of a square is 2 km . How long is each side of the square?

Question

To find the length of each side of a square when you know the perimeter, you can use the following formula:

$$
\text{Perimeter of a square} = 4 \times \text{side length}
$$

Given:
$$
\text{Perimeter} = 2\ \text{km}
$$

Let's denote the side length of the square as $$ s $$. Plugging the known perimeter into the formula:

$$
2\ \text{km} = 4 \times s
$$

To solve for $$ s $$, divide both sides of the equation by 4:

$$
s = \frac{2\ \text{km}}{4} = 0.5\ \text{km}
$$

**Therefore, each side of the square is 0.5 kilometers long.**

*Alternatively, you can express this length in meters:*

$$
0.5\ \text{km} = 500\ \text{meters}
$$

So, each side of the square is **500 meters** long.
Each side of the square is 0.5 kilometers (or 500 meters) long.
