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

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.
