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.


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 find the distance from corner to corner on a rectangle?

Diagonal of a rectangle or square = square root of ( length2 + width2 )


How do you find area of square if diagonal is given?

Using Pythagoras' theorem which says that the square on the hypotenuse (in this case the diagonal) is equal to the sum of the squares on the other two sides (which in the case of a square would be equal in length). so if the diagonal measured 10 units, the square on the diagonal would be 100 square units. And as this = 2*the squares on the other sides, the square on one side would be 100/2 = 50 square units. As a square has sides of equal length the square on one side is actually the area of the square. i.e. the area of a square with a diagonal of 10 units is 50 square units. or generically the area of a square with a diagonal of length 'x' = (x2)/2


Find the area of a square with a diagonal of 6 yds?

You can use trigonometry to find the solution. A diagonal divides a square into two triangles, known as "45-45-90" triangles (because of the measures of each angle). According to a law of the same name, the hypotenuse (side opposite of the 90o angle) has a length equal to the length of a leg (side opposite of a 45o angle) times the square root of two. So, since the hypotenuse is a diagonal, you will find that the length of each side of the square is 6 divided by the square root of 2. Find the square of this, and you have the total area: 18 square yards.

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.

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.

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 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.

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


Find the diagonal of a square?

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