Answer 3

Finding the Area of a Square with a Given Perimeter

To find the area of a square, we need to know the length of one side. In this case, we are given the perimeter of the square, which is 36 cm.

The perimeter of a square is calculated by multiplying the length of one side by 4. So, if we let s represent the length of one side, we can set up the equation:

4s = 36

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

s = 36 / 4

Simplifying the equation, we get:

s = 9

Therefore, the length of one side of the square is 9 cm.

Calculating the Area of the Square

Now that we know the length of one side of the square is 9 cm, we can calculate the area of the square.

The area of a square is calculated by squaring the length of one side. In this case, the length of one side is 9 cm, so we can set up the equation:

Area = s^2

Substituting the value of s, we get:

Area = 9^2

Simplifying the equation, we get:

Area = 81

Therefore, the area of the square is 81 square cm.

I hope this helps! Let me know if you have any further questions.
