Answer 2

Perimeter and Area of a Square

To find the area of a square, we first need to know the perimeter of the square. The perimeter of a square is the sum of all its sides. In this case, the perimeter of the square is given as 48 dm.

Perimeter of a square = 4 * side length

From the given information, we can set up the equation:

48 dm = 4 * side length

To find the side length, we can divide both sides of the equation by 4:

side length = 48 dm / 4 = 12 dm

Now that we know the side length of the square is 12 dm, we can calculate the area of the square.

Area of a square = side length * side length

Substituting the value of the side length into the formula:

Area = 12 dm * 12 dm = 144 dm²

Therefore, the area of the square is 144 square decimeters.
