Final answer:
The perimeter of a square with a side length of 0.5 is calculated by multiplying the side length by 4, which gives 2 units as the perimeter.
Step-by-step explanation:
The question asks about the perimeter of a square where the side length is 0.5. To calculate the perimeter of a square, we multiply the length of one side by 4, since a square has four sides of equal length. Therefore, if the side length is 0.5, the formula to find the perimeter would be:
Perimeter = side length × 4
Plugging in the numbers:
Perimeter = 0.5 × 4 = 2
So, the perimeter of a square with a side length of 0.5 is 2 units.
