Using Pythagoras' theorem each side measures 3.536 units rounded to 3 decimal places
If the length of a side of the square is S units then the diagonal is S*sqrt(2) units in length.
The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
The length of the diagonal of a square whose side lengths are 7 square root 2 (9.89949494) is: 14 units.
Using Pythagoras' theorem each side will be 6.363961031 units in length.
The diagonal is 33.941 units.
If the length of a side of the square is S units then the diagonal is S*sqrt(2) units in length.
About 11.31 units.
sqrt(12.5) units
The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
d=x√2 where d is a diagonal and x is a side d=80√2 (or 113.137)
The length of the diagonal of a square whose side lengths are 7 square root 2 (9.89949494) is: 14 units.
Use Pythagoras' therom: 32+32 = 18 The square root of 18 is 4.242640687 units which is the length of the diagonal.
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
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.
Using Pythagoras' theorem each side will be 6.363961031 units in length.
The diagonal length = 7.07 inches.
