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
What is length of diagonal line in rectangle 32 feet by 36 feet?
Using Pythagoras: 322+362 = 2320 and the square root of this is the length of the diagonal
How long is diagonal of 24' x 48' rectangle?
Using Pythagoras theorem: 53.665' correct to 3 dp
What is the length of a diagonal line in a rectangle 30 feet by 20 feet?
You can calculate this using the Pythagorean formula for a right triangle.
What is the diagonal of a 5 feet by 10 feet area?
Assuming you are talking about a rectangular area, the diagonal would be found using the Pythagorean Theorem. 5^2 + 10^2 = d^2, so 125 = d^2, then take square root of both sides. This means the diagonal is approximately 11.18 feet. It is exactly 5√5 feet.
How do you prove that the diagonals of a rectangle are congruent using vectors?
If the vectors emanting from one corner of the rectangel are called a and b then. (a) + (b) = one diagonal (a) + (-b) = the other diagonal and |(a) + (b)| = |(a) + (-b)| (the absolute value of the diagonal's scalars are equal)
If QRST below is a rectangle with QT equal to 15 and QR equal to 25 then TR is approximately equal to 29.15?
Using Pythagoras' theorem the diagonal of the rectangle is about 29.15 units in length
What is the length of the diagonal of a square with sides that have a length of 1 unit?
Using Pythagoras' theorem the answer is equal to the square root of 2.

What is the area of a square with a diagonal of 14?
Using Pythagoras: diagonal² = side² + side² = 2 × side² → side² = diagonal² ÷ 2 area = side² = diagonal² ÷ 2 = 14² ÷ 2 = 98 units²
What is the length of the diagonal of a square with an area of 36?
Using Pythagoras: diagonal² = side² + side² = 2 × side² → side² = diagonal² ÷ 2 area = side² = diagonal² ÷ 2 → diagonal² = 2 × area → diagonal = √(2 × area) = √(2 × 36) = 6√2 ≈ 8.49
What is the diagonal of a square that has a 16' side?
Using Pythagoras' theorem the diagonal is 16 times the square root of 2
What is length of diagonal line in rectangle 32 feet by 36 feet?
Using Pythagoras: 322+362 = 2320 and the square root of this is the length of the diagonal
What are some real life examples of using a diagonal line?
Some charts? Buildings Obtuse triangle - some of them are diagonal.
How Long is the diagonal of a 9x 12 Rectangular picture frame?
Using Pythagoras' theorem the length of the diagonal is 15 units
How do you find the volume of a cubical box when diagonal is given?
Cool question ! Answer - half it then cube it to prove it - an example for you if cube diagonal (not square diagonal) is 100, then using pythagoras theorm the square diagonal = 70.71068, If square the square diagonal = 70.71068, then using pythagoras theorm the side length = 50 therefore the volume = 50 ^ 3 = 25000 units works with any numbers
Is the diagonal of a square the same as its side?
Not always, the diagonal can be figured out using the Pythagorean Theorem (a²+b²=c²). Where the diagonal is the hypotenuse (c). By rearranging the Pythagorean Theorem, you can see that the diagonal of a square is always 1.4 times the side of the square.
