Answer 3

Finding the Area of a Square

To find the area of a square, you need to know the length of one of its sides. In this case, the perimeter of the square is given as 36 cm.

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

Let's calculate the length of one side first:

Perimeter of the square = 36 cm Length of one side = Perimeter / 4 = 36 cm / 4 = 9 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) x (Length of one side)

Area of the square = 9 cm x 9 cm = 81 cm²

Therefore, the area of the square is 81 cm².
