Calculation of the Perimeter Increase of a Square

To calculate the increase in the perimeter of a square when its side length is increased by 2 cm, we need to understand the relationship between the side length and the perimeter of a square.

The perimeter of a square is calculated by multiplying the length of one side by 4. Therefore, if we increase the side length of a square by 2 cm, the new side length will be the original side length plus 2 cm.

Let's denote the original side length of the square as x cm. The new side length will be x + 2 cm.

To calculate the increase in the perimeter, we subtract the original perimeter from the new perimeter:

Increase in perimeter = New perimeter - Original perimeter

The original perimeter is calculated as 4 * x cm, and the new perimeter is calculated as 4 * (x + 2) cm.

Substituting these values into the equation, we get:

Increase in perimeter = 4 * (x + 2) - 4 * x

Simplifying the equation, we have:

Increase in perimeter = 4x + 8 - 4x

The 4x terms cancel out, leaving us with:

Increase in perimeter = 8 cm

Therefore, when the side length of a square is increased by 2 cm, the perimeter of the square increases by 8 cm.

Please note that the above calculation is based on the assumption that the square is a perfect geometric shape and that the increase in the side length is uniform across all sides.
