By the Pythagorean Theorem, it's simply L*Sqrt(2), where L is the length of the side, and Sqrt denotes the square root.

What is the formula to find one side of a square?

The answer will depend on what information about the square you have: its perimeter, area, length of diagonal.


How do you find the side of a square if you know its diagonal?

Divide the length of the diagonal of a square by 1.4142 (which is the square root of 2) to find the length of a side. Similarly, to find the length of the diagonal of a square, multiply the length of a side by 1.4142.


What is the diagonal of a 33 inch square?

Use Pythagoras' theorem to find the length of the diagonal in the square


How is the length of a diagonal of a square found?

As a square has right angles, the diagonal forms a right triangle with two of the sides of the square. Therefore use Pythagoras: diagonal² = side² + side² → diagonal² = 2side² → diagonal = side × √2 Therefore to find the length of the diagonal of a square, multiply the side length of a square by the square root of 2.


What is the formula to find the diagnal of a square?

diagonal = square root ( side squared + side squared) = square root (2) x side (pythagorean theorem since angle is 90degrees)

How do you find the length of a rectangle knowing ONLY the diagonal and the width?

You square the width and subtract it from the diagonal squared. Then find the square root of this number, this number is now the length.


When you know the sum of lengths of diagonal of a square how to find each diagonal?

To find the length of each diagonal of a square, divide the sum of the diagonal lengths by 2. Since a square has two diagonals of equal length, this division will give you the length of each diagonal.


If you have the diagonal and with of a rectangle how do you find the Perimeter?

Square the diagonal and take away the square of width, this gives you the square of the other side. Add the square root of the two sides and multiply by two.


How do you work out diagonal of a square?

How do you find the diagonal of a square?

If you know the length of the side, multiply it by the square root of 2.


What is the length of the diagonal of a square with an area of 64?

To find the length of the diagonal of a square with an area of 64 square units, we first need to calculate the side length of the square. Since the area of a square is side length squared (A = s^2), we can find the side length by taking the square root of the area (s = āˆšA). In this case, the side length of the square is 8 units. To find the length of the diagonal, we can use the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides (a^2 + b^2 = c^2). Since a square can be divided into two right triangles with the diagonal as the hypotenuse, we can calculate the diagonal length using d = āˆš(s^2 + s^2), where d is the diagonal length and s is the side length. Substituting the side length of 8 units into the formula, we get d = āˆš(8^2 + 8^2) = āˆš(64 + 64) = āˆš128 = 8āˆš2 units. Therefore, the length of the diagonal of a square with an area of 64 square units is 8āˆš2 units.
