What is Meant by Rectangle Diagonal?

In Maths, rectangle is a two-dimensional shape with four sides. A rectangle is a quadrilateral whose opposite sides are parallel and equal. Also, the angles at four vertices equal to right angles. The diagonal of a rectangle divides the rectangle into two congruent right triangles. Hence, the diagonal can be found using Pythagoras theorem. Where, diagonal acts as hypotenuse, sides are considered as the base and perpendicular. The formula to find the diagonal of a rectangle is:
Diagonal = √(l2 + b2)
l = Length of the rectangle
b = Breadth of the rectangle
