What is the formula for calculating the diagonal length of a rectangle?

Answers

The formula for calculating the diagonal length \( d \) of a rectangle is derived from the Pythagorean theorem. If \( w \) is the width and \( h \) is the height (or length) of the rectangle, the diagonal can be calculated using the following formula:

\[
d = \sqrt{w^2 + h^2}
\]

Where:
- \( d \) is the length of the diagonal,
- \( w \) is the width,
- \( h \) is the height.

You simply square the width and height, add those two values together, and then take the square root of the result to find the diagonal length.
