Sqrt(576 + 1296) = sqrt 1872 = sqrt 9 x sqrt 13 x sqrt 16 = 12 root 13 = 43' 3.2"
Use Pythagoras' therorem to find the diagonal of the rectangle which is 12 times the sq rt of 13
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 know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
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
Cubic measurements are found by multipying width by length by height. If a box measures 3 ft wide by 2 ft long by 1 ft high it is 6 cubic feet.
The diagonal is 25 feet.
Use Pythagoras' therorem to find the diagonal of the rectangle which is 12 times the sq rt of 13
You multiply the 3 measurements
After converting all the measurements to the same units, you would use the Pythagoras Theorem.
18.9 feet
18.9 feet
The diagonal line forms two triangles, each with one side 34 feet long and one side 30 feet long. Use Pythagorean Theorem to find the length of the diagonal line which is the hypotenuse of the triangles. a^2 + b^2 = c^2 Where a and b are the sides of the triangle and c is the hypotenuse. (34)^2 + (30)^2 = c^2 1156 + 900 = c^2 2056 = c^2 45.34 = c So, the diagonal line is 45.34 feet.
The side length of a regular octagon whose principal diagonal is 25 feet is 9.57 feet, approx.
That depends how exactly the measurements of the sides are - and how exactly the "right angle" is really a right angle. If the measurements are exact, then, yes, you can also calculate the diagonal exactly - using Pythagoras' Theorem..................................................................................................................................Improved Answer:No it's not possible to find the accurate length of the diagonal of any square using Pythagoras' theorem because the answer will always be an irrational number which can never be determined just like the value of pi in a circle.
There are a number of websites that have converters for feet to meters measurements. One can find them on 'Metric Conversions', 'Online Conversion' and 'SI Metric'.
Take the measurements of two adjoining walls and multiply for the result.
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
