Answer 2

Perimeter of a Square

To find the perimeter of a square, we need to know the length of one side of the square. In this case, the length of one side of the square is given as 25mm.

The formula to calculate the perimeter of a square is:

Perimeter = 4 * side length

Given that the side length of the square is 25mm, we can substitute this value into the formula to find the perimeter.

Perimeter = 4 * 25mm

To convert the result to decimeters, we need to divide the perimeter by 10, as there are 10 millimeters in a decimeter.

Let's calculate the perimeter:

Perimeter = 4 * 25mm = 100mm

To convert the result to decimeters:

Perimeter in decimeters = 100mm / 10 = 10 decimeters

Therefore, the perimeter of the square with a side length of 25mm is 10 decimeters.
