How do you find the length of the diagonal of a square side?
The diagonal of square formula = a√2; where ‘a’ is the side length. The given side length is substituted in this formula to get the length of the diagonal. For example, if the side length of a square is given as 10 cm, we will substitute the value in the formula, d = a√2.
What is the formula for finding the length of a diagonal?
You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: d² = l² + w² , and now you should know how to find the diagonal of a rectangle explicit formula – just take a square root: d = √(l² + w²) .
What is the shortcut to find the length of the diagonal?
So, the length of the diagonal of a square is given as x√2 units.
