Final answer:
The lateral area of a square is 4 times the length of one side.
Step-by-step explanation:
The lateral area of a square is the sum of the areas of its four sides. Since all sides of a square are equal, we can find the lateral area by multiplying the length of one side by the number of sides. So, the lateral area of a square is 4 times the length of one side.
In this case, since the question does not provide the length of the side of the square, we cannot calculate the lateral area. Therefore, we cannot determine if options a, b, or c are correct.
