To find the diagonal dimension, you must find the length of the hypotenuse
The formula to find the hypotenuse is a2 + b2 = c2. Since we know that both the legs are twenty feet long, then we can fill in the formula.
202 + 202 = c2
400 + 400 = c2
800 = c2
c = √800
c ≈ 28.28
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.
You need to include the third dimension to calculate the cubic capacity of a room
The diagonal measurement of an 18 x 18 square is: 25.46 units.
400 square feet.
The diagonal of a 12' x 24' rectangle is approx 26.8'.
The diagonal is 20.
Use Pythagoras: Diagonal² = √(2 × sidelength²) → diagonal = side_length × √2 → diagonal = 20 × √2 ≈ 28.3 units
One size is 15 feet by 20 feet. Divide 300 by any number. The number is the first dimension. The answer will be the other dimension. Example: 300/12=25. This room is 12 x 25 feet.
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.
53.85164807' by means of Pythagoras.
The diagonal dimension of a tv screen that is 20W x 15H is 25 inches. Formula is a-squared + b-squared = c-squared
12' x 20"
The average dimension of a family room is 14 square feet. i.e.4.0 metres x 3.5 metres .
A 20 x 20 room will have a perimeter of 20 + 20 + 20 + 20 = 80.
Using Pythagoras it is 20 times square root of 2
About 28.28 feet.
It could be many dimensions, 6 x 8 for example.
