A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).

Which is length and which is breadth?

Width or breadth usually refer to a shorter dimension when length is the longest one. Depth is used for the third dimension of a three dimensional object.

Which side is the breadth of a rectangle?

It is a two-dimensional geometric shape in which the opposite sides are parallel and equal to each other and all four angles are right angles. The shorter side of a rectangle is called its breadth (width) and the longer side is the length.
