Oct 13, 2025 by wbrum.org 8 views

Introduction

In this problem, we are given the area of a square window, which is 6 m². We need to find the exact perimeter of the window. To solve this problem, we will use the formula for the area of a square and the formula for the perimeter of a square.

The Area of a Square

The area of a square is given by the formula:

A = s²

where A is the area of the square and s is the length of one side of the square.

The Perimeter of a Square

The perimeter of a square is given by the formula:

P = 4s

where P is the perimeter of the square and s is the length of one side of the square.

Finding the Side Length of the Square Window

We are given that the area of the window is 6 m². We can use this information to find the side length of the window.

A = s²

6 = s²

To find the side length, we need to take the square root of both sides of the equation.

s = √6

s ≈ 2.45 m

Finding the Perimeter of the Square Window

Now that we have found the side length of the window, we can use the formula for the perimeter of a square to find the perimeter of the window.

P = 4s

P = 4(2.45)

P ≈ 9.80 m

Conclusion

In this problem, we were given the area of a square window, which is 6 m². We used the formula for the area of a square and the formula for the perimeter of a square to find the exact perimeter of the window. We found that the side length of the window is approximately 2.45 m, and the perimeter of the window is approximately 9.80 m.

Conclusion

Q: What is the formula for the area of a square?

A: The formula for the area of a square is A = s², where A is the area of the square and s is the length of one side of the square.

Q: What is the formula for the perimeter of a square?

A: The formula for the perimeter of a square is P = 4s, where P is the perimeter of the square and s is the length of one side of the square.

Q: How do I find the side length of a square given its area?

A: To find the side length of a square given its area, you need to take the square root of both sides of the equation A = s². This will give you the value of s, which is the length of one side of the square.

Q: What if I don't have a calculator to find the square root?

A: If you don't have a calculator, you can estimate the square root by finding two perfect squares that are close to the given area. For example, if the area is 6 m², you can find that 4² = 16 and 3² = 9, so the square root of 6 is between 3 and 4.

Q: Can I use the formula for the perimeter of a square to find the side length?

A: No, you cannot use the formula for the perimeter of a square to find the side length. The formula for the perimeter of a square is P = 4s, and you need to know the side length to find the perimeter. To find the side length, you need to use the formula for the area of a square, A = s².

Q: What if the area of the square is not a perfect square?

A: If the area of the square is not a perfect square, you will need to use a calculator to find the square root of the area. This will give you the value of s, which is the length of one side of the square.

Q: Can I use the formula for the perimeter of a square to find the area?

A: No, you cannot use the formula for the perimeter of a square to find the area. The formula for the perimeter of a square is P = 4s, and you need to know the side length to find the perimeter. To find the area, you need to use the formula for the area of a square, A = s².

Q: What if I make a mistake when finding the side length or perimeter?

A: If you make a mistake when finding the side length or perimeter, you will need to recheck your work and make sure that you are using the correct formulas and values. It's also a good idea to check your work by plugging in the values you find into the original equation to ensure that they are correct.

Q: Can I use the formula for the perimeter of a square to find the diagonal of the square?

A: No, you cannot use the formula for the perimeter of a square to find the diagonal of the square. The formula for the perimeter of a square is P = 4s, and you need to know the side length to find the perimeter. To find the diagonal of the square, you need to use the Pythagorean theorem, which is d² = s² + s², where d is the diagonal of the square and s is the length of one side of the square.

Conclusion

In conclusion, finding the perimeter of a square window given its area requires the use of formulas and the ability to take square roots. By following the steps outlined in this article, you can solve similar problems and develop a deeper understanding of the relationship between the area and perimeter of a square.
