Diagonal = sqrt (twice the square of a side)
eg: square of side 8 units, d = sqrt(2 x 64)
= sqrt 128 = 11.3137

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.
How do you work out diagonal of a square?
It is the longest distance between two opposite corners of the square and it is possible to use Pythagoras' theorem to find the length of the diagonal
How do you find the area of a square given only the length of its diagonal?
Given the length of the diagonal of the square ... call it 'D units'. The area of the square is (1/2 D2) (same units)2.
What is the perimeter of a square with diagonal 12 centimeters?
The perimeter of a square with a diagonal of 12 centimeters is: 33.9 centimeters.In future, to find out the perimeter of a square when you only know it's diagonal, use Pythagoras or times the diagonal by 2.828427125.This number is irrational, and is like a pi for the diagonals of squares.I call it Tau.It is the relationship between the diagonal of all squares and there perimeter.
Find the area of a square with a diagonal of 8cm?
32 cm² = 8cm²/2
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.
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.
Square area equals 8 hectare find diagonal in km?
The square has a diagonal measurement of: 1.13 km
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?
It is the longest distance between two opposite corners of the square and it is possible to use Pythagoras' theorem to find the length of the 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.
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.
The length of a diagonal of a square is 24square root 2 millimeters find perimeter of the square?
The perimeter of a square with a diagonal length of 24 square root 2 millimeters (33.94 mm) is: 96 mm
If you have height and diagonal measurement of a rectangle how do you find width?
The square of the diagonal minus the square of the height would equal the square of the width. Therefore the square root of the solution to the above problem would be the width
