Rectangle

Perimeter of a Rectangle Formula is given as,

\[\large Perimeter\;of\;a\;Rectangle=2(Length+Width)\]

Solved Examples

Example: Find the perimeter of rectangle whose length is 9 cm and width is 16 cm.

Solution:

Given,
Length = 9 cm
Width = 16 cm

Perimeter of Rectangle= 2(Length + Width)
= 2(9 + 16) cm
= 2 x 25 cm
= 50 cm

Example: Find the perimeter of a rectangle whose length and width is 20 cm and 9 cm respectively.
Solution:
Given,
Length = 20 cm
Width = 9 cm
Perimeter of Rectangle = 2(Length + Width)
= 2(20 +9) cm
= 2 x 29 cm
= 58 cm
