Which of these values would be the perimeter of a square with each side measuring 4 units?

The perimeter of a square is calculated by adding together the lengths of all four sides. Since a square has equal side lengths, the formula for the perimeter can be simplified to multiplying the length of one side by 4. In this case, if each side measures 4 units, you would compute the perimeter as follows:

Perimeter = 4 (units per side) × 4 (sides) = 16 units.

This calculation clearly shows that the correct answer represents the total distance around the square, which is 16 units. Understanding this formula helps clarify how the dimensions of shapes contribute to their overall measurements, making it an essential concept in geometry.
