Answer:
144 square inches.
Explanation:
The perimeter of a square is equal to the sum of the lengths of all its sides. If a square has a perimeter of 48 inches, then each side is 48/4 = 12 inches long.
The area of a square is equal to the square of the length of its sides. Therefore, the area of the square is:
Area = side x side = 12 inches x 12 inches = 144 square inches.
So the area of the square is 144 square inches.
