Perimeter and Area of a Square

To find the area of a square, we need to know the length of one of its sides. In this case, we are given that the perimeter of the square is 28 cm.

The perimeter of a square is the sum of all its sides. Since a square has four equal sides, we can divide the perimeter by 4 to find the length of one side.

Let's calculate the length of one side:

Perimeter of the square = 28 cm Length of one side = Perimeter / 4 = 28 cm / 4 = 7 cm

Now that we know the length of one side, we can find the area of the square. The area of a square is calculated by multiplying the length of one side by itself.

Area of the square = Length of one side * Length of one side = 7 cm * 7 cm = 49 cm²

Therefore, the area of the square with a side length of 7 cm is 49 cm².
