Answer: 2x + 0.5 unit
Explanation:
A square has 4 equal sides. Therefore, its perimeter is calculated by adding the four sides.
Since the perimeter of a square is 8x +2 units, to get the length of one side, we divide the perimeter by 4. This will be:
= (8x + 2)/4
= 2x + 0.5
Therefore, the length of one side is 2x + 0.5 unit
