Answer 2

Perimeter of a Square

To find the length of each side of a square given its perimeter, we can use the formula:

Perimeter = 4 * side length

In this case, the perimeter of the square is given as 76 dm. We need to find the length of each side.

Let's calculate it step by step:

1. We know that the perimeter of the square is 76 dm. 2. We can use the formula mentioned above to find the length of each side. 3. Substitute the given perimeter into the formula:

76 dm = 4 * side length

4. Solve for the side length:

side length = 76 dm / 4

side length = 19 dm

Therefore, the length of each side of the square is 19 dm.
