Let x equal the length of the square. Let y equal the length of the diagonal. Two times (x squared) = (y squared).
Answer:
You have to use Pythagorus' relationship of the sides of a right angled triangle to the hypotenuse.
It states that the sum of the squares of the sides (A2 + B2 ) equals the square of the hypotenuse (C2):
A2 + B2 = C2
In the case given, the hypotenuse is the diagonal of the square and the sides are all equal so
A2 + A2 = C2
or 2A2 = C2
reorganizing to get the length of the diagonal on one side:
SQRT(C2) = SQRT (2A2) = SQRT 2 x SQRT A2
or C = SQRT 2 x A
The side is therefore always the length of the diagonal divided by the square root of 2 (approximately 1.1442)

If you know the length of a side of a quare how can you determine the length of the diagonal?
Multiply by the square root of 2.
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 know the length of a side of a square how do you find the length of its diagonal?
To find the length of the diagonal of a square, use the Pythagorean Theorem (a^2 + b^2 = c^2) ... You know that "a" and "b" are the same in this case, so it becomes square_root of 2 x (side_length2) ... which you can simplify as "multiply by the square root of 2"
What is the diagonal length of square when sides are 5 in length?
If you are familiar with Pythagoras's theorem you will know that it is 5x5 + 5x5 => 25 + 25=50 find the square root of fifty and you will have your answer
How do you determine area when perimeter and length of a square is given?
The perimeter of square is 4 x length If you have perimeter only divide by 4 to get length and The area of square is length x length If you already have length that is all you need to know
If you know the length of a side of a quare how can you determine the length of the diagonal?
Multiply by the square root of 2.
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.
How do you find lengths of sides of square when know length of its diagonal?
A square has 4 sides of equal length (say x). The diagonal length = x * (2)^0.5 = 1.414x, from Pythagorus's theorem. So, dividing the diagonal length by the square root of 2 will be the answer.
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.
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.
The area of a square is 100 The length of its diagonal is approximately?
If the area of a square is 100, then its side length is 10. If we draw in a diagonal, then we know by the Pythagorean formula that the diagonal's length is sqrt(10^2 + 10^2) = sqrt(200) = 10*sqrt(2).The square root of 2 is approximately 1.414, so the diagonal's length is approximately 10*1.414 =14.14* The diagonal of any square is the side length times (sq rt 2).
If a square is inscribed in a circle the diameter of the circle is congruent to?
The diameter of the circle is congruent to the length of the diagonal of the inside square. If you know the length of one side of the square, you can use pythagorean's theorem to solve for its diagonal (hypotenuse) and thusly the square's diameter.
If you know the length of a side of a square how do you find the length of its diagonal?
To find the length of the diagonal of a square, use the Pythagorean Theorem (a^2 + b^2 = c^2) ... You know that "a" and "b" are the same in this case, so it becomes square_root of 2 x (side_length2) ... which you can simplify as "multiply by the square root of 2"
What is the diagonal length of square when sides are 5 in length?
If you are familiar with Pythagoras's theorem you will know that it is 5x5 + 5x5 => 25 + 25=50 find the square root of fifty and you will have your answer
How do you find the diagonal of a rectangle if you know the length and the angle?
You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
How can you find the length of a diagonal without measuring i?
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
How do you determine area when perimeter and length of a square is given?
The perimeter of square is 4 x length If you have perimeter only divide by 4 to get length and The area of square is length x length If you already have length that is all you need to know
