If the length of a side of the square is S units then the diagonal is S*sqrt(2) units in length.
Approximately 17 feet.
Approximately 10 inches.
You multiply the length of a side by the square root of 2.If you only have the area, square root it to find the length of a side.
It depends on the relationship between the triangle and the square!
Using Pythagoras' theorem it is about 4.243 feet rounded to 3 decimal places
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.
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.
The diagonal length = 7.07 inches.
Since a square has right angles, you can use the Pythagorean Theorem to calculate the diagonal. Specifically, the diagonal of a square is equal to the length of a side, multiplied by the square root of 2.
The diagonal length of a square with a 900 square foot area is: 42.43 feet.
The perimeter = 12 feetthen the square diagonal = 12/4 = 3 feet The diagonal2 = 3x3 + 3x3= 18 feetThe diagonal = square root of 18 = 3x 21/2 feet = 3 x 1.4142 = 4.2426 feet
