- Perimeter of a Rectangle
The longer side of a rectangle is usually called the length, and the shorter side is the breadth.
length = l
breadth = b
Perimeter of rectangle = \( \scriptsize l \: + \: b \: + \: l \: + \: b \\ = \scriptsize l \: + \: l \: + \: b \: + \: b \\ = \scriptsize 2l \: + \: 2b \\ = \scriptsize 2(l \: + \: b) \)
Perimeter of a Rectangle = 2l + 2b
Where l = Length
b = breadth
breadth (b) is also known as width (w)
Example 7.3.1:
The length of a rectangular room is 8 m, and the width (breadth) is 6 m. Find the perimeter of the room.
Solution:
Length of the room, l = 8 m
