What p/b means in geometry

P/b in geometry stands for perimeter/breadth. It is a ratio used to measure the shape of an object. This ratio is calculated by dividing the perimeter of the object (the length of all sides combined) by its breadth (the width of the object). The resulting number will give you an indication of the shape of the object. For example, a square has a p/b ratio of 4, while a rectangle has a p/b ratio of 2. This ratio can be used to compare different shapes and determine which shape has the greatest perimeter relative to its breadth.
