About this calculation

The diagonal of a rectangle is a straight line segment that connects two opposite corners or vertices of the rectangle. It is the longest possible straight-line distance that can be measured inside the rectangle, passing through its center.

Formula

To calculate the rectangle diagonal length, you can use the following formula.

Diagonal Length = \({\ \sqrt{ l ^2 + w ^2}\ }\)
