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.


What is the diagonal of a 33 inch square?

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


How do you find out the length of a diagonal in a square?

Use Pythagoras. The diagonal, and two sides of the square form a right angled triangle. So if each side of the square is x cm long, the diagonal is x*sqrt(2) cm long.


What is the formula to find the diagonal of a rectangle?

The diagonal of a rectangle is the third and longest side of a triangle with sides the same as those of the rectangle, so its length is the square root of the sum of the squares of the lengths of the sides of the triangle, (Pythoagoras' Theorem) which are also the sides of the rectangle. If the rectangle is 3 inches by 4 inches, then the diagonal is the square root of 3 squared (= 9) and 4 squared (= 16) so the diagonal is the square root of 16 + 9 = 25, giving it the length of 5 inches.


What is the perimeter of a square whose one diagonal is 16cm?

To find the perimeter of a square with a diagonal of 16 cm, we first need to determine the side length of the square using the Pythagorean theorem. The diagonal of a square divides it into two right-angled triangles, with the diagonal being the hypotenuse. Using the formula a^2 + b^2 = c^2, where a and b are the two sides of the triangle and c is the hypotenuse, we can calculate that each side of the square is 8√2 cm. Since a square has four equal sides, the perimeter is 4 times the side length, giving us a perimeter of 32√2 cm.

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 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.


What is the diagonal measurement of a square 24 feet x 24 feet?

Ah, what a lovely question! To find the diagonal measurement of a square, we can use the Pythagorean theorem. So, for a square that is 24 feet by 24 feet, we can use the formula diagonal = √(side length squared + side length squared). Plugging in the values, we get diagonal = √(24^2 + 24^2) = √(576 + 576) = √1152 ≈ 33.94 feet.


How do you work out diagonal of a square?
